In a “third party next hop" network, that is, the local router has two IPv6 multicast eBGP peers in
a broadcast network, the router does not specify itself as the next hop of routes sent to the
EBGP peers by default.
Follow these steps to specify the router as the next hop of routes sent to a peer/peer group:
To do… Use the command… Remarks
Enter system view system-view —
Enter BGP view bgp as-number —
Enter IPv6 MBGP address
family view
ipv6-family multicast —
Configure the router as the next
hop of routes sent to the
peer/peer group
peer { ipv6-group-name |
ipv6-address } next-hop-local
Optional
By default, IPv6 MBGP specifies
the local router as the next hop
for routes sent to an eBGP
peer/peer group, but not for
routes sent to an iBGP
peer/peer group.
Configuring the AS_PATH Attribute
Follow these steps to configure the AS_PATH attribute:
To do… Use the command… Remarks
Enter system view system-view —
Enter BGP view bgp as-number —
Enter IPv6 MBGP address
family view
ipv6-family multicast —
Allow the local AS number to
appear in the AS-PATH of
routes from a peer/peer group
and specify the number of times
that the local AS number can
appear in the AS-PATH of
routes from the peer/peer group
peer { ipv6-group-name |
ipv6-address } allow-as-loop
[ number ]
Optional
Not allowed by default
Disable IPv6 MBGP from
considering the AS_PATH
during best route selection
bestroute as-path-neglect
Optional
Enabled by default
