3. Configure BGP to ignore
IGP metrics during optimal
route selection.
bestroute igp-metric-ignore
By default, BGP considers IGP
metrics during optimal route
selection. If multiple routes to
the same destination are
available, BGP selects the
route with the smallest IGP
metric as the optimal route.
Configuring the SoO attribute
After you configure the SoO attribute for a BGP peer or peer group, BGP adds the SoO attribute into
the route updates received from the BGP peer or peer group. In addition, before advertising route
updates to the peer or peer group, BGP checks the SoO attribute of the route update against the
configured SoO attribute. If they are the same, BGP does not advertise the route updates to the BGP
peer or peer group.
To configure the SoO attribute (IPv4 unicast/multicast address family):
1. Enter system view.
