Configuring PIM-SSM GRE Selective Provider Tunnels
This topic describes how to configure a PIM-SSM GRE selective provider tunnel for an MBGP MVPN.
Creating a selective provider tunnel enables you to move high-rate traffic off the inclusive tunnel and deliver the multicast traffic only to receivers that request it. This improves bandwidth utilization.
To configure a PIM-SSM GRE selective provider tunnel for the
224.0.113.1/24
customer multicast group address, the 10.2.2.2/32 customer source address, and a
virtual routing instance named
green
.
Since we are using addresses outside the reserved SSM address range of 232.0.0.0/8,
we must also include the group-range
address with the
pim-ssm
option.
When configuring PIM-SSM GRE selective provider tunnels, keep the following in mind:
Aggregation of multiple customer multicast routes to a single PIM S-PMSI is not supported.
Provider tunnel multicast group addresses must be IPv4 addresses, even in configurations in which the customer multicast group and source are IPv6 addresses.
