Version 32.3 adds the ability to configure IPv4 Protocol Independent Multicast (PIM) traffic over GRE tunnels. PIM control packets are exchanged between GRE tunnel endpoints across the GRE tunnel, forming a PIM neighborship across the GRE tunnel. Similar to IPv4 unicast support on GRE tunnels, multicast data packets are routed from a tenant interface to the far end of the IPv4 GRE tunnel. The IPv4 next-hop for the multicast packets is the IPv4 tunnel IP of the BGP neighbor.
ExtremeSwitching X590, X465, and X695 series switches, and on X590 and X465 series stacks.
This feature has the following limitations:
The following new CLI commands support this feature:
configure pim {ipv4} add {tunnel} [tunnel_name | tunnel all] {sparse | dense} {passive}
configure pim {ipv4} delete tunnel [tunnel_name | tunnel all]
configure pim {ipv4} timer hello_interval jp_interval [{tunnel} tunnel_name | tunnel all]
configure pim {ipv4} [{tunnel} tunnel_name | tunnel all] dr-priority priority
disable ipmcforwarding {tunnel tunnel_name}
disable pim {ipv4} ssm tunnel [tunnel_name | tunnel all]
enable ipmcforwarding {tunnel tunnel_name}
enable pim {ipv4} ssm tunnel [tunnel_name | tunnel all]
show pim tunnel
unconfigure pim {ipv4}{tunnel tunnel_name}
