Configuring The Med Attribute; Configuring The As_Path Attribute - HP 6125G Configuration Manual

In a third party next hop network where the two IPv6 EBGP peers reside in a common broadcast
•
subnet, the router does not change the next hop for routes sent to the IPv6 EBGP peer or peer group
by default, unless the peer next-hop-local command is configured.
To configure IPv6 BGP preference and default LOCAL_PREF and NEXT_HOP attributes:
Step
1. Enter system view.
2. Enter BGP view.
3. Enter IPv6 address family
view.
4. Configure preference values
for IPv6 BGP external,
internal, and local routes.
5. Configure the default local
preference.
6. Advertise routes to an IPv6
peer or peer group with the
local router as the next hop.

Configuring the MED attribute

Step
1. Enter system view.
2. Enter BGP view.
3. Enter IPv6 address family
view.
4. Configure a default MED
value.
5. Enable the comparison of
MED for routes from different
EBGP peers.
6. Enable the comparison of
MED for routes from each AS.
7. Enable the comparison of
MED for routes from
confederation peers.
