Configuring a Selective Provider Tunnel Using Wildcards
When you configure a selective provider tunnel for MBGP MVPNs (also referred to as next-generation Layer 3 multicast VPNs), you can use wildcards for the multicast group and source address prefixes. Using wildcards enables a PE router to use a single route to advertise the binding of multiple multicast streams of a given MVPN customer to a single provider's tunnel, as described in http://tools.ietf.org/html/draft-rekhter-mvpn-wildcard-spmsi-00 .
Sharing a single route improves control plane scalability because it reduces the number of S-PMSI autodiscovery routes.
To configure a selective provider tunnel using wildcards:
- Configure a wildcard group matching any group IPv4 address
and a wildcard source for (*,*) join messages.[edit routing-instances vpna provider-tunnel selective]user@router# set wildcard-group-inet wildcard-source
- Configure a wildcard group matching any group IPv6 address
and a wildcard source for (*,*) join messages.[edit routing-instances vpna provider-tunnel selective]user@router# set wildcard-group-inet6 wildcard-source
- Configure an IP prefix of a multicast group and a wildcard
source for (*,G) join messages.[edit routing-instances vpna provider-tunnel selective]user@router# set group 224.0.0/24 wildcard-source
- Map the IPv4 join messages to a selective provider tunnel.[edit routing-instances vpna provider-tunnel selective wildcard-group-inet wildcard-source]user@router# set rsvp-te (Routing Instances Provider Tunnel Selective) label-switched-path-template provider-tunnel1
- Map the IPv6 join messages to a selective provider tunnel.[edit routing-instances vpna provider-tunnel selective wildcard-group-inet6 wildcard-source]user@router# set rsvp-te (Routing Instances Provider Tunnel Selective) label-switched-path-template provider-tunnel2
- Map the (*,224.0.0/24) join messages to a selective provider
tunnel.[edit routing-instances vpna provider-tunnel selective group 224.0.0/24 wildcard-source]user@router# set rsvp-te (Routing Instances Provider Tunnel Selective) label-switched-path-template provider-tunnel3
