3.8.4 IPv4 routing information cannot be found in VRF
If the routing information of each protocol cannot be found in the routing information obtained by
the Switch, isolate the cause of the problem according to the failure analysis method described in
the following table.
Table 3-22: Failure analysis method for VRF
If the configuration is not correct, modify the configuration. For
details about the procedure for checking the filter configuration
information, see 3.25.1 Checking the filters and QoS configuration
information.
No. Items to check and commands Action
1 Check whether the number of routes in
VRF is equal to or larger than the
maximum value specified in the
configuration.
show ip vrf
If the number of routes is equal to or larger than the maximum value,
go to No. 2.
If the number of routes is less than the maximum value, perform the
failure analysis for the protocol for the route that does not exist.
For RIP, see 3.8.1 No RIP routing information exists.
For OSPF, see 3.8.2 No OSPF routing information exists.
For BGP4, see 3.8.3 No BGP4 routing information exists.
2 Check the maximum number of routes in
VRF specified in the configuration.
Increase the maximum number, or reduce the number of routes by,
for example, aggregating the routes.
