Configuring the MED attribute
When other conditions of routes to a destination are identical, the route with the smallest MED is
selected.
To configure the MED attribute:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter BGP view. bgp as-number N/A
3. Enter IPv4 MBGP address family
view.
ipv4-family multicast N/A
4. Configure the MED attribute.
• Configure the default MED value:
default med med-value
• Enable the comparison of the MED
of routes from different Ass:
compare-different-as-med
• Enable the comparison of the MED
of routes from each AS:
bestroute compare-med
• Enable the comparison of the MED
of routes from confederation peers:
bestroute med-confederation
Optional.
The default MED value is 0.
Not enabled by default.
Configuring the NEXT_HOP attribute
You can use the peer next-hop-local command to specify the local switch as the next hop of routes sent
to a MBGP IBGP peer or peer group. If load balancing is configured, the switch specifies itself as the next
hop of route advertisements to the multicast IBGP peer or peer group regardless of whether the peer
next-hop-local command is configured.
In a "third party next hop" network, that is, when the local switch has two multicast EBGP peers in a
broadcast network, the switch does not specify itself as the next hop of routing information sent to the
EBGP peers unless the peer next-hop-local command is configured.
To specify the switch as the next hop of routes sent to a peer/peer group:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter BGP view. bgp as-number N/A
3. Enter IPv4 MBGP address family
view.
ipv4-family multicast N/A
