DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide Usage Guideline The user can use the BGP ORF (Outbound Route Filtering) capability to reduce the number of prefixes exchanged with the peer. Typically, the command must be configured in pair on the local router and the remote router. The function can operate in one direction or in both directions. When it operates in one direction, the prefix list used as for the ingress filtering on one router will be sent to the peer router and act as the egress prefix list filtering applied to routes to be sent out from the peer router. The first router should be configured as send mode and the peer router should be configured as receive mode. When the ingress prefix list on the first router is changed, to reflect the change to the peer router, the user should issue the clear bgp in prefix-list command on the peer router. Example In the following example, router A (10.20.30.5) is configured with ingress prefix list and is enabled for send mode and router B is enabled for receive mode. Router B (10.20.40.10) installs the egress prefix list from router by the clear bgp in prefix-filter command for the neighbor session. Router A: Switch# configure terminal Switch(config)# router bgp 65100 Switch(config-router)# neighbor 10.20.40.10 remote-as 65200 Switch(config-router)# neighbor 10.20.40.10 prefix-list CUSTOMER in Switch(config-router)# neighbor 10.20.40.10 capability orf prefix-list send Router B: Switch# configure terminal Switch(config)# router bgp 65200 Switch(config-router)# neighbor 10.20.30.5 remote-as 65100 Switch(config-router)# neighbor 10.20.30.5 capability orf prefix-list receive Switch(config-router)# exit Switch(config)# exit Switch# clear ip bgp 10.20.30.5 soft in prefix-filter 12-49 neighbor default-originate (MI and EI Mode Only) This command is used to generate a default route to a neighbor. Use the no form of this command to disable generating the default route or disable the conditional injection. neighbor {IP-ADDRESS | IPV6-ADDRESS | PEER-GROUP-NAME} default-originate [route-map MAPNAME] no neighbor {IP-ADDRESS | IPV6-ADDRESS | PEER-GROUP-NAME} default-originate Parameters IP-ADDRESS IPV6-ADDRESS PEER-GROUP-NAME route-map MAP-NAME Specifies the IP address of the neighboring peer. Specifies the IPv6 address of the neighboring peer. Specifies the name of the BGP peer group. (Optional) Specifies the name of a route map to achieve conditional injection of default route. Default No default route is sent to the neighbor. 203
