TABLE 120

This field...

Displays...

LOCAL_PREF

For information about this field, refer to the table above.

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 or RIPng.

When BGP4+ compares multiple routes to a destination to select the best route,
IGP is preferred over EGP and both are preferred over INCOMPLETE.

Weight

For information about this field, refer to the table above.

AS-PATH

For information about this field, refer to the table above.

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 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::106, enter the following command.

device# show ipv6 bgp neighbor 2001:db8::106 routes best

There are 2 accepted routes from neighbor 2001:db8::106

The best keyword displays the "best" routes, which are installed in the IPv6 route table.

The unreachable keyword displays the routes whose destinations are unreachable using any of the
BGP4+ paths in the IPv6 route table.
