Configuring Inbound Route Filtering; Configuring Ipv6 Bgp And Igp Route Synchronization - HPE FlexNetwork HSR6800 Configuration Manual

Configuring inbound route filtering

Only routes passing the configured filtering can be added into the local IPv6 BGP routing table.
Members of a peer group can have different inbound route filtering policies.
To configure inbound route filtering:
Step
Enter system view.

Enter BGP view.

Enter IPv6 address family

Configuring IPv6 BGP and IGP route synchronization

By default, upon receiving an IBGP route, an IPv6 BGP router checks the route's next hop. If the next
hop is reachable, the IPv6 BGP router advertises the route to EBGP peers. If the synchronization
feature is configured, in addition to the reachability check of the next hop, the IPv6 BGP router must
find an active IGP route with the same destination network segment before it can advertise the IBGP
route (use the display ipv6 routing-table protocol command to check the IGP route state).
To configure IPv6 BGP and IGP route synchronization:
Step
Enter system view.
1.
Enter BGP view.
2.
Enter IPv6 address family view.
