Enabling The Ipv6 Mbgp Orf Capability - HP A5500 SI Switch Series Configuration Manual

The current IPv6 MBGP implementation supports the route-refresh feature that enables dynamic route
refresh without terminating IPv6 MBGP connections.
However, if a peer that does not support route refresh exists in the network, you must configure the peer
keep-all-routes command to save all routes from the peer. When the routing policy is changed, the
system will update the IPv6 MBGP routing table and apply the new policy.
Soft reset through route-refresh
If the peer is enabled with route refresh, when the IPv6 MBGP route selection policy is modified on a
router, the router advertises a route-refresh message to its IPv6 MBGP peers, which resend their routing
information to the router after they receive the message. Therefore, the local router can perform dynamic
route update and apply the new policy without terminating IPv6 MBGP connections.
Follow these steps to configure IPv6 MBGP soft reset through route-refresh:
To do...
Enter system view
Enter BGP view
Enter IPv6 address family view
Enable IPv6 BGP route refresh for
a peer/peer group
Perform a manual soft-reset
If the peer does not support route refresh, use the peer keep-all-routes command to save all the route
updates from the peer, and then use the refresh bgp ipv6 multicast command to soft-reset IPv6 MBGP
connections to refresh the IPv6 MBGP routing table and apply the new policy without terminating IPv6
MBGP connections.
Follow these steps to perform a manual soft-reset
To do...
Enter system view
Enter BGP view
Enter IPv6 address family view
Enter IPv6 MBGP address family
view
Keep all routes from a peer/peer
group regardless of whether they
pass the inbound filtering policy
Soft-reset IPv6 MBGP connections
manually

Enabling the IPv6 MBGP ORF capability

The BGP Outbound Route Filter (ORF) feature enables a BGP speaker to send a set of ORFs to its BGP
peer through route-refresh messages. The peer then applies the ORFs, in addition to its local routing
Use the command...
system-view
bgp as-number
ipv6-family
peer { ipv6-group-name | ipv6-
address } capability-advertise
route-refresh
Use the command...
system-view
bgp as-number
ipv6-family
ipv6-family multicast
peer { ipv6-group-name | ipv6-
address } keep-all-routes
refresh bgp ipv6 multicast { all |
ipv6-address | group ipv6-group-
name | external | internal } {
export | import }
