RIP Export Policy Conditions for Specified Interfaces
Table 76 lists the policy conditions for the RIP export policies:
Multiple Matched Routing Policies
Because you can use a wildcard parameter (
all
) to specify a source or
target route, there are times when several policies can apply to the same
route.
When the module perceives that there is more than one policy for the
same route, it follows this hierarchy of rules to resolve the policy conflict:
■
The policy with the highest administrative weight
■
The policy that matches the specific source
■
The policy that matches the most number of bits for the route
■
The policy that matches the origin protocol
■
The policy with the lowest index
