R211x-HP Flexfabric 11900 Layer 3 - IP Routing Command Reference

Usage guidelines
IMPORTANT:
Ignoring the ORIGINATOR_ID attribute might introduce routing loops to the network. Do not use this
command to ignore the ORIGINATOR_ID attribute if you are not sure there are no routing loops.
A router is configured with a router ID. When a router receives a BGP route update, it compares the router
ID with the ORIGINATOR_ID attribute in the route update. If they are the same, the router drops the route
update to avoid routing loops. However, for some networks (such as firewall networks) to operate
correctly, BGP must not drop but accept such route updates. For BGP to accept such route updates, you
must configure BGP to ignore the ORIGINATOR_ID attribute in BGP route updates.
After you execute this command, BGP also ignores the CLUSTER_LIST attribute.
Examples
# In BGP view, configure BGP to ignore the ORIGINATOR_ID attribute in BGP route updates from the
p e e r 1.1.1.1.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] peer 1.1.1.1 ignore-originatorid
# In BGP VPN instance view, configure BGP to ignore the ORIGINATOR_ID attribute in BGP route
updates from the peer 1.1.1.1.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ip vpn-instance vpn1
[Sysname-bgp-vpn1] peer 1::1 ignore-originatorid
peer keep-all-routes
Use peer keep-all-routes to save all route updates from a peer or peer group, regardless of whether the
routes have passed the configured routing policy.
Use undo peer keep-all-routes to restore the default.
Syntax
In BGP IPv4 unicast address family view/BGP-VPN IPv4 unicast address family view/BGP VPNv4
address family view:
peer { group-name | ip-address } keep-all-routes
undo peer { group-name | ip-address } keep-all-routes
In BGP IPv6 unicast address family view:
peer { group-name | ipv6-address } keep-all-routes
undo peer { group-name | ipv6-address } keep-all-routes
