Specifying the PIM VRF Rendezvous Point (RP) Address
To specify the PIM VRF RP address, perform this task:
When specifying the PIM VRF RP address, note the following information:
• vrf vrf_name—(Optional) Specifies a particular VRF instance to be used.
• rp_address—Unicast IP address for the PIM RP router.
• access_list—(Optional) Number or name of an access list that defines the multicast groups for the
RP.
• override—(Optional) In the event of conflicting RP addresses, this particular RP overrides any RP
that is learned through Auto-RP.
• bidir—(Optional) Specifies that the multicast groups specified by the access_list argument are to
operate in bidirectional mode. If this option is not specified, the groups operate in PIM sparse mode.
• Use bidirectional mode whenever possible, because it offers better scalability.
This example show how to specify the PIM VRF RP address:
Router(config)# ip pim vrf blue rp-address 198.196.100.33
Configuring a Multicast Source Discovery Protocol (MSDP) Peer
To configure an MSDP peer, perform this task:
When configuring an MSDP peer, note the following information:
• vrf vrf_name—Specifies a particular VRF instance to be used.
• {peer_name | peer_address}—Domain Name System (DNS) name or IP address of the MSDP peer
router.
• connect-source interface_type interface_number—Interface name and number for the interface
whose primary address is used as the source IP address for the TCP connection.
• remote-as ASN—(Optional) Autonomous system number of the MSDP peer. This is for
display-only purposes.
Command or Action Purpose
Router(config)# ip pim vrf
vrf_name
rp-address
rp_address
[
access_list
] [override] [bidir]
Specifies the PIM RP IPv4 address for a (required for sparse
PIM networks):
Router(config)# no ip pim vrf
vrf_name
rp-address
rp_address
Clears the PIM RP IPv4 address.
Command or Action Purpose
Router(config)# ip msdp vrf
vrf_name
peer {
peer_name
|
peer_address
} [connect-source
interface_type
interface_number
] [remote-as
ASN
]
(Optional) Configures an MSDP peer.
Router(config)# no ip msdp vrf
vrf_name
peer
{
peer_name
|
peer_address
} [connect-source
interface_type
interface_number
] [remote-as
ASN
]
Clears the PIM RP IPv4 address.
