This display shows the following information.
Displaying the best and unreachable routes received from a BGP4+ neighbor
You can display a summary or detailed information about the following types of BGP4+ routes
received from a specified neighbor:
•
Best routes – The “best” routes to their destinations, which are installed in the Virtual ADX
device’s IPv6 route table.
•
Unreachable – The routes whose destinations are unreachable using any of the BGP4+ paths
in the IPv6 route table.
For example, to display a summary of the best routes to a destination received from neighbor
2001:db8:2000:4::106, enter the following command.

LOCAL_PREF
For information about this field, refer to
MED
The value of the RIB route’s MED attribute. If the route does not have a metric,
this field is blank.
Origin
The source of the route information. The origin can be one of the following:
•
EGP – The routes with this set of attributes came to BGP4+ through EGP.
•
IGP – The routes with this set of attributes came to BGP4+ through IGP.
•
INCOMPLETE – The routes came from an origin other than one of the
above. For example, they may have been redistributed from OSPFv3.
When BGP4+ compares multiple routes to a destination to select the best
route, IGP is preferred over EGP and both are preferred over INCOMPLETE.
