Dell EMC SmartFabric OS10 User Guide Release 10.5.1

• ip-address—Enter the IPv4 or IPv6 address of the neighbor.
• interface interface-type—Enter the interface that connects to an unnumbered neighbor.
• unnumbered-auto—Configure one or more BGP auto unnumbered neighbors.

Create a remote peer with the BGP neighbor.

If you configure an unnumbered interface using the interface option, ensure that the interface is in Layer 3 mode. Also, enable Router Advertisement on required interfaces using the ipv6 nd send-ra command. If you do not enable Router Advertisement, the BGP neighborship does not form. Dell EMC networking recommends configuring the minimum and maximum advertisement intervals as 3 s and 4 s, respectively.

The no version of this command disables the BGP neighbor configuration.

The following is an example for configuring an unnumbered BGP neighbor:

OS10(config)# interface vlan 100
OS10(conf-if-vl-100)# ipv6 nd max-ra-interval 4
OS10(conf-if-vl-100)# ipv6 nd min-ra-interval 3
OS10(conf-if-vl-100)# ipv6 nd send-ra
OS10(conf-if-vl-100)# exit
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# no shutdown
OS10(conf-if-eth1/1/1)# switchport mode trunk
OS10(conf-if-eth1/1/1)# switchport trunk allowed vlan 100
OS10(config)# router bgp 100
OS10(config-router-bgp-100)# neighbor interface vlan 100
OS10(config-router-neighbor)# no shutdown
