Dell EMC SmartFabric OS10 User Guide Release 10.5.1

OS10 provides multiple ways to aggregate routes in the BGP routing table. At least one route of the aggregate must be in the routing table for the configured aggregate route to become active. AS_SET includes AS_PATH and community information from the routes that are included in the aggregated route.

1. Assign an AS number in CONFIGURATION mode.

   router bgp as-number

2. Enter Address Family mode in ROUTER-BGP mode.

   address-family {[ipv4 | ipv6] [unicast]}

3. Aggregate address in ROUTER-BGPv4-AF mode.

   aggregate-address ip-address/mask 

Configure aggregate routes

OS10(config)# router bgp 105
OS10(conf-router-bgp-105)# address-family ipv4 unicast 
OS10(conf-router-bgpv4-af)# aggregate-address 3.3.0.0/16

View running configuration

OS10(conf-router-bgpv4-af)# do show running-configuration bgp
