Dell EMC SmartFabric OS10 User Guide Release 10.5.0

You can change the value of the LOCAL_PREFERENCE attributes for all routes the router receives. To change the LOCAL_PREF value in ROUTER-BGP mode from 0 to 4294967295 with default 100, use the default local preference value command.

To view the BGP configuration, use the show running-configuration command. A more flexible method for manipulating the LOCAL_PREF attribute value is to use a route-map.

1. Assign a name to a route map in CONFIGURATION mode.

   route-map map-name {permit | deny | sequence-number}

2. Change the LOCAL_PREF value for routes meeting the criteria of this route map in ROUTE-MAP mode, then return to CONFIGURATION mode.

   set local-preference value
   exit

3. Enter ROUTER-BGP mode.

   router bgp as-number

4. Enter the neighbor to apply the route map configuration in ROUTER-BGP mode.

   neighbor {ip-address}

5. Apply the route map to the neighbor’s incoming or outgoing routes in ROUTER-BGP-NEIGHBOR-AF mode.

   route-map map-name {in | out)

6. Enter the peer group to apply the route map configuration in ROUTER-BGP mode.

   template template-name

7. Apply the route map to the peer group’s incoming or outgoing routes in CONFIG-ROUTER-TEMPLATE-AF mode.

   route-map map-name {in | out}
