Recommendations on avoiding nested tunneling

Announce policy.
Configure a policy rule on the receiving tunnel endpoint (router 2) that will cause the
receiving endpoint to block advertisements of the source network (192.68.1.0) in its routing
updates. This will prevent the source endpoint (router 1) from learning the route. This
solution is for nested tunneling caused by RIP. For example, using the network shown in
Figure 37
activate it on the router RIP with the matching interface:
G350-001(super)# ip distribution access-list-name 1 "list #1"
Done!
G350-001(super)# ip distribution access-default-action 1 default-action-permit
Done!
G350-001(super)# ip distribution access-list 1 10 "deny" 192.68.1.0 0.0.0.255
Done!
G350-001(super)# router rip
G350-001(super router:rip)# distribution-list 1 out FastEthernet 10/2
Done!
G350-001(super router:rip)# exit
G350-001(super)#
