Non-equivalence link partial equipment run OSPF automatic switch SLA test

I. Overview:

QQ Group of a Netizen consulted three places through the MSTP line 22 interconnection, are Cisco equipment, but one of them does not support OSPF, ask if the normal situation, the data to go 8M line, but the 8M link problems when the 4M backup link, and then use GNS3 to build the environment test a bit, Brush up on the SLA settings.

Two. Basic ideas:

A. Static routing priority dynamic OSPF routing, static routing configuration of different metric values, and setting SLAs

B. Backup link because it can run dynamic routing, the static route is distributed to dynamic routing, which ensures that any one line of three lines will fail without affecting the access of the three networks.

Three. Test topology:

Four. Basic configuration:
