Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Filtering routes allows you to implement BGP policies. Use route-maps to control which routes the BGP neighbor or peer group accepts and advertises.

1. Enter the neighbor IP address to filter routes in ROUTER-BGP mode.

   neighbor ipv4-address

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

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

3. Create a route-map and assign a filtering criteria in ROUTER-BGP-NEIGHBOR-AF mode, then return to CONFIG-ROUTER-BGP mode.

   route-map map-name {in | out}
   exit

   • in—Enter a filter for incoming routing updates.
   • out—Enter a filter for outgoing routing updates.
4. Enter a peer template name in ROUTER-BGP mode.

   template template-name

5. Enter Address Family mode.

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

6. Create a route-map, and assign a filtering criteria in ROUTER-BGP-TEMPLATE-AF mode.

   route-map map-name {in | out}
