Usage Guideline
This command is used to prevent routing loops between routers within a VPN.
In the VPN, the most typical application lies in that the two CE ends have the same
AS number. Normally, these two CE routers can’t receive the other from the other
party, because the BGP protocol will not receive the route information with the same
AS number in AS path attribute as the AS of BGP instance itself. After the above
command is configured on the PE router, you can let the PE replace the AS number
of the CE to AS number of PE self, so that the CE from the other end can receive the
route information. Only set this function for the EBGP peer.
Use the
show ip bgp neighbors
or
show ip bgp peer-group
command to verify
your settings.
Example
This example shows how to enable AS override flag of BGP peer 3.3.3.3 in VRF
vpn1
.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)# router bgp 10
DXS-3600-32S(config-router)# address-family ipv4 vrf vpn1
DXS-3600-32S(config-router-af)# neighbor 3.3.3.3 remote-as 20
DXS-3600-32S(config-router-af)# neighbor 3.3.3.3 as-override
