DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide Example This example shows how to set the maximum prefixes that will be accepted from the neighbor, 192.168.1.1 to 1000. Switch# configure terminal Switch(config)# router bgp 40000 Router(config-router)# network 192.168.0.0 Router(config-router)# neighbor 192.168.1.1 maximum-prefix 1000 Switch(config-router)# 13-55 neighbor next-hop-self (MI and EI Mode Only) This command is used to configure the router as the next hop for a BGP-speaking neighbor or peer-group. Use the no form of this command to disable this feature. neighbor {IP-ADDRESS | IPV6-ADDRESS | PEER-GROUP-NAME} next-hop-self no neighbor {IP-ADDRESS | IPV6-ADDRESS | PEER-GROUP-NAME} next-hop-self Parameters IP-ADDRESS IPV6-ADDRESS PEER-GROUP-NAME Specifies the IP address of the BGP-speaking neighbor. Specifies the IPv6 address of the neighboring peer. Specifies the name of a BGP peer group. Default By default, this option is disabled. Command Mode Router Configuration Mode. Address Family Configuration Mode (IPv4 Unicast, IPv6 Unicast, and VRF). Address Family Configuration Mode (IPv4 Multicast, L2VPN VPLS and VPNv4). (MI Mode Only) Command Default Level Level: 12. Usage Guideline To advertise a route to an eBGP peer, the BGP router will use the original next hop of the advertised route as the next hop if the original next hop is in the same subnet as the router's advertising interface. This will create problem if the attaching interface is an unmeshed network where BGP neighbors may not have direct access to all other neighbors on the same IP subnet. Use the neighbor next-hop-self command to use the router's self IP address as the next-hop of the routes for this case. Example This example shows how to force all updates destined for 10.108.1.1 to advertise this router as the next hop. Switch# configure terminal Switch(config)# router bgp 40000 Router(config-router)# neighbor 10.108.1.1 next-hop-self Router(config-router)# 224
