Default-Route Imported (Ipv6 Address Family View/Ipv6 Bgp-Vpn Instance View) - HP FlexNetwork 3600 v2 Series Command Reference Manual

undo default med
View
IPv6 address family view, IPv6 BGP-VPN instance view
Default level
2: System level
Parameters
med-value: MED value, in the range of 0 to 4294967295.
Description
Use default med to specify the default MED value.
Use undo default med to restore the default.
By default, the default med-value is 0.
The multi-exit discriminator (MED) is an external metric of a route. Different from local preference,
MED is exchanged between ASs and will stay in the AS once it enters the AS. The route with a lower
MED is preferred. When a router running BGP obtains several routes with the identical destination
and different next-hops from various external peers, it will select the best route depending on the
MED value. In the case that all other conditions are the same, the system first selects the route with
the smaller MED value as the best route for the autonomous system.
Examples
# Devices A and B belong to AS100 and device C belongs to AS200. C is the peer of A and B.
Configure the MED of A as 25 to make C select the path from B.
