DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide Example This example shows how to set the 'allowas-in' value to 3 without the NUMBER parameter. DXS-3600-32S#configure terminal DXS-3600-32S(config)#router bgp 100 DXS-3600-32S(config-router)#neighbor 100.16.5.4 remote-as 65101 DXS-3600-32S(config-router)#neighbor 100.16.5.4 allowas-in DXS-3600-32S(config-router)# 7-38 neighbor as-override This command is used to enable to override the AS number of a site with the provider's AS number on a PE router. Use the no form of the command to disable this function. neighbor {IP-ADDRESS | PEER-GROUP-NAME} as-override no neighbor {IP-ADDRESS | PEER-GROUP-NAME} as-override Parameters IP-ADDRESS PEER-GROUP-NAME Specifies the address of the peer. Specifies the name of the peer group, Default Command Mode Command Default Level Usage Guideline Disabled. Address Family Configuration (VRF). Level: 8. (EI Mode Only Command) 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 7-39 neighbor capability orf prefix-list This command is used to advertise outbound router filter (ORF) capabilities to a peer or a peer group. Use the no form of this command to disable ORF capabilities. neighbor {IP-ADDRESS | PEER-GROUP-NAME} capability orf prefix-list {receive | send | both} no neighbor {IP-ADDRESS | PEER-GROUP-NAME} capability orf prefix-list {receive | send | both} 92
