Routing Policies Configuring BGP
page 4-52 OmniSwitch 6800/6850/9000 Advanced Routing Configuration Guide December 2007
Reconfiguring Peer Policies
You can configure policies and assign these policies to a BGP peer, either to control in-bound routes or
out-bound routes advertisement. Additionally, it is possible to change or modify these peer policies, after
they are assigned to a peer.
Once the policies have been modified, they have to be re-applied to the peer. To re-apply the policies to
only the peer under consideration, you can use the in-reconfigure and the out-reconfigure commands.
To reconfigure a peer’s in policies, enter the peer’s IP address with the ip bgp neighbor clear soft
command as shown:
-> ip bgp neighbor 172.22.2.0 clear soft in
To reconfigure a peer’s out policies, enter the peer IP address with the ip bgp neighbor clear soft
command, as shown:
-> ip bgp neighbor 172.22.2.0 clear soft out
