Configuring Ipv6 Mbgp Community; Configuring An Ipv6 Mbgp Route Reflector - HP A5500 SI Switch Series Configuration Manual

CAUTION:
To create an IPv6 MBGP peer group, you need to enable an existing IPv6 unicast peer group in IPv6
MBGP address family view.
Before adding an IPv6 MBGP peer to the IPv6 MBGP peer group, you need to add the corresponding
IPv6 BGP unicast peer to the corresponding IPv6 BGP unicast peer group.

Configuring IPv6 MBGP community

A peer group enables a group of peers to share the same policy, and a community enables a group of
IPv6 MBGP routers in multiple ASs to share the same policy. The community attribute is propagated
among IPv6 MBGP peers and not restricted to AS boundaries.
You can reference a routing policy to modify the community attribute for routes sent to a peer. In
addition, you can define extended community attributes as needed.
Follow these steps to advertise the community attribute to an IPv6 MBGP peer/peer group:
To do...
Enter system view
Enter BGP view
Enter IPv6 MBGP address family
view
Advertise the community attribute
to an IPv6 MBGP peer/peer
group
Advertise the extended community
attribute to an IPv6 MBGP
peer/peer group
Apply a routing policy to routes
sent to an IPv6 MBGP peer/peer
group
NOTE:
You need to configure a routing policy to define the community attribute and apply the policy to
outgoing routes.
For routing policy configuration, see the

Configuring an IPv6 MBGP route reflector

To guarantee connectivity between IPv6 multicast iBGP peers, you need to make them fully meshed.
Howerver, this becomes impractical when too many IPv6 multicast iBGP peers exist. Using route
reflectors can solve the problem.
Follow these steps to configure an IPv6 BGP route reflector:
Use the command...
system-view
bgp as-number
ipv6-family multicast
peer { ipv6-group-name | ipv6-
address } advertise-community
peer { ipv6-group-name | ipv6-
address } advertise-ext-
community
peer { ipv6-group-name | ipv6-
address } route-policy route-
policy-name export
