3Com Switch 8800 Configuration Guide
[SwitchA-bgp-af-mul] network 1.0.0.0
[SwitchA-bgp-af-mul] network 2.0.0.0
[SwitchA-bgp-af-mul] quit
Configure peers relationship.
[SwitchA-bgp] bgp 100
[SwitchA-bgp] group a1 external
[SwitchA-bgp] peer 192.1.1.2 group a1 as-number 200
[SwitchA-bgp] group a2 external
[SwitchA-bgp] peer 193.1.1.2 group a2 as-number 200
[SwitchA-bgp] ipv4-family multicast
[SwitchA-bgp-af-mul] peer a1 enable
[SwitchA-bgp-af-mul] peer a2 enable
Configure the MED attribute of Switch A.
Add an ACL on Switch A to permit network 1.0.0.0.
[SwitchA] acl number 2000
[SwitchA-acl-basic-2000] rule permit source 1.0.0.0 0.255.255.255
[SwitchA-acl-basic-2000] rule deny source any
Define two routing policies: set_med_50 and set_med_100, providing two MED
values for network 1.0.0.0 (50 and 100 respectively).
[SwitchA] route-policy set_med_50 permit node 10
[SwitchA-route-policy] if-match acl 2000
[SwitchA-route-policy] apply cost 50
[SwitchA-route-policy] quit
[SwitchA] route-policy set_med_100 permit node 10
[SwitchA-route-policy] if-match acl 2000
[SwitchA-route-policy] apply cost 100
Apply the routing policy set_med_50 to the exported route updates of Switch C
(193.1.1.2). Apply the routing policy set_med_100 to the exported route updates
of Switch B (192.1.1.2).
[SwitchA] bgp 100
[SwitchA-bgp] ipv4-family multicast
[SwitchA-bgp-af-mul] peer a2 route-policy set_med_50 export
[SwitchA-bgp-af-mul] peer a1 route-policy set_med_100 export
2) Configure Switch B:
[SwitchB] vlan 20
[SwitchB-vlan20] port ethernet2/1/2
[SwitchB-vlan20] quit
[SwitchB] interface vlan-interface 20
[SwitchB-Vlan-interface20] ip address 192.1.1.2 255.255.255.0
[SwitchB-Vlan-interface20] quit
[SwitchB] vlan 40
[SwitchB-vlan40] port ethernet2/1/4
