Configuring BGP Routing Policy
For BGP, you can specify the following:
external Reverts to the normal BGP rules for propagating the MED; this is
the BGP default
internal Sets the MED of a received route that is being propagated to an
external peer equal to the IGP cost of the indirect next hop
Example
host1(config)#route-map nyc1 permit 10
host1(config-route-map)#set metric-type internal
Use the no version to delete the set clause from a route map.
See set metric-type.
Use to set the BGP origin of the advertised route.
Example
host1(config)#route-map nyc1 permit 10
host1(config-route-map)#set origin egp
Use the no version to delete the set clause from a route map.
See set origin.
Use to set the tag value of the destination routing protocol.
Example
host1(config)#route-map nyc1 permit 10
host1(config-route-map)#set tag 23
Use the no version to delete the set clause from a route map.
See set tag.
Use to specify the BGP weight for the routing table.
The weights assigned with the set weight command in a route map override the
weights assigned using the neighbor weight and neighbor filter-list weight
commands.
Example
host1(config)#route-map nyc1 permit 10
host1(config-route-map)#set weight 200
Use the no version to delete the set clause from a route map.
See set weight.
