ip multicast-routing [ distributed ]
Enables IP multicast forwarding. The distributed keyword enables multicast distributed fast switching chassis-wide on boxes that support distributed fast switching.
ip pim ssm [ default | range <acl> ]
Configures the SSM-range. If default argument is used, range = 232/8.
ip pim rp-address <ip-address> [ <group-access-list> ] [ override ]
Statically configures the PIM Rendezvous Point (RP) address for a particular group range (default 224/4). If the override argument is present, this static config will take precedence over RPs learned via Auto-RP.
ip pim accept-register list <acl> | route-map <map>
Configures a filter for PIM register messages accepted by the RP. For example, <acl> could filter register messages for the SSM space. When a Register message is denied, an immediate Register-Stop is sent back to the originator of the Register.
ip mroute <source> <mask> <rpf-address>
Configures a multicast static route (aka a "static mroute"). The <rpf-address> argument will be used to determine incoming interface for sources matching the mroute. <rpf-address> can be a directly connected PIM neighbor or a route for recursive lookup.
ip igmp static-group <group> [ source <source> ]
Creates static entry in IGMP groups table for this interface. This will cause traffic for the multicast group <group> to be statically forward traffic to this interface. Can be useful for debugging.
ip igmp version 1|2|3
Configures the IGMP version in use on this interface. Default is version 2. IGMP is enabled by PIM configuration on the interface.
ip cgmp
Enables proprietary Cisco Group Management Protocol on this interface. Requires PIM be enabled on this interface.
ip pim version 1|2
Configures PIM version for this interface. Default is 2.
ip pim sparse-mode
Enables PIM-SM on this interface.
ip pim bsr-border
Configures the interface to be the PIM domain border. PIM-SMv2 bootstrap messages will be dropped bidirectionally by this interface. This should be configured on all external interfaces.
ip multicast boundary <acl>
Configures an administratively scoped boundary on the interface for multicast group addresses matching the simple IP access-list <acl>. No multicast data packets will be allowed to flow across the boundary from either direction.
neighbor <address> remote-as <asn> [ nlri unicast | multicast ]
Configures an MBGP peer. Supplying both keywords "unicast" and "multicast" indicates both NLRI are configured for this peer. The default value of NLRI is unicast only. MBGP will negotiate NLRI in the Capabilities Option of the Open message.
neighbor <tag> peer-group [ nlri unicast | multicast ]
Configures the peer-group to support either unicast NLRI, multicast NLRI or both. Supplying both keywords "unicast" and "multicast" indicates both NLRI are sent. The default value is unicast only.
network <address> [mask <mask>] [nlri unicast | multicast]
Determines if network in the AS should be injected into the BGP unicast RIB or the MBGP multicast RIB. If both keywords "unicast" and "multicast" are specified, it is injected in both RIBs. If "multicast" is specified, it is injected in the multicast RIB only. The default is unicast only.
router bgp <id>
neighbor <addresses> remote-as <asn>
address-family ipv4 multicast
neighbor { <addresses> | <peer-group-name> } activate
network <address> [mask <mask>] [route-map <map>]
exit-address-family
address-family ipv4 unicast
neighbor { <addresses> | <peer-group-name> } activate
network <address> [mask <mask>] [route-map <map>]
exit-address-family
neighbor <address> remote-as <asn>
Configures an MBGP peer. Use one or more address family statements to configure information specific to each address family (ipv4 unicast, ipv4 multicast, ipv6 unicast, vrf, etc).
address-family ipv4 unicast
Places the router in address family configuration mode (prompt: config-router-af), from which you can configure peerings for IPv4 unicast NLRI. To leave address family configuration mode and return to router configuration mode, type exit. Upon configuring a BGP session w/ the 'neighbor <address> remote-as <asn>' command, IPv4 unicast NLRI is advertised by default.
address-family ipv4 multicast
Places the router in address family configuration mode (prompt: config-router-af), from which you can configure peerings for IPv4 multicast NLRI. To leave address family configuration mode and return to router configuration mode, type exit.
address-family <addr-family> neighbor <addresses> | <peer-group-name> } activate
Enables exchange of NLRI for the enclosing address family with specified neighbor.
address-family <addr-family> network <address> [mask <mask>] [route-map <map>]
Specifies networks that should be injected into MBGP RIB (unicast, multicast, etc) specified by the enclosing address family statement.
ip msdp peer <ip-address> [connect-source <interface>] [remote-as <asn>]
Configures an MSDP peer. The keyword "connect-source" is used to supply a source IP address for the TCP connection. The primary address configured on <interface> is used.
ip msdp description <peer> <text>
This command adds a descriptive text string <text> to the configuration.
ip msdp shutdown <peer>
This command administratively shuts down a peer.
ip msdp sa-filter out <peer> [list <acl>] [route-map <map>]
[ { rp-list <rp-acl> | rp-route-map <rp-map> } ]
Configures outgoing filter list for Source-Active messages sent to MSDP peer <peer>. The default setting is all SA messages received are forwarded to the peer. <acl> is an extended access-list that can describe source/group pairs to pass through the filter. The rp-list and rp-route-map keywords allow the filtering of SAs by originating RP. For example, send only SAs originated by the local RP.
ip msdp sa-filter in <peer> [list <acl>] [route-map <map>]
[ { rp-list <rp-acl> | rp-route-map <rp-map> } ]
Same as above for Source-Active messages received from MSDP peer <peer>.
ip msdp sa-limit <peer> <limit>
Configure this command to limit the overall number of Source-Actives the router will accept from MSDP peer <peer>. This command was introduced as a mean of protection against denial of service attacks.
ip msdp redistribute [list <acl>]
Configures which (S,G) entries from the multicast routing table are advertised in SA messages to MSDP peers. By default only local sources are advertised. If "list <acl>" is used, you can further filter what local sources are advertised (and to what groups they send to) by using the extended access-list <acl> where you can supply a source address, source mask, group address and group mask.
