Configuration procedure
1. Configure IP addresses for the interfaces on each router and configure IS-IS.
Follow Figure 58 to c
onfigure the IP address and subnet mask of each interface. (Details not
shown.)
Configure IS-IS on the routers, ensuring that Router A, Router B, Router C, and Router D can
communicate with each other at Layer 3 and dynamic route update can be implemented among
them with IS-IS. (Details not shown.)
2. Configure MTR:
# Create a rule for advanced IPv4 ACL 3001 to permit packets with DSCP value 11 to pass.
<RouterA> system-view
[RouterA] acl number 3001
[RouterA-acl-adv-3001] rule permit ip dscp 11
[RouterA-acl-adv-3001] quit
# Create a rule for advanced IPv4 ACL 3002 to permit packets with DSCP value 22 to pass.
[RouterA] acl number 3002
[RouterA-acl-adv-3002] rule permit ip dscp 22
[RouterA-acl-adv-3002] quit
# Create topologies voice and video. Specify ACL 3001 for topology voice, and ACL 3002 for
topology video.
[RouterA] address-family ipv4
[RouterA-address-family ipv4] multiple-topology voice
[RouterA-multiple-topology-voice] acl 3001
[RouterA-multiple-topology-voice] quit
