Announce policy Configure a policy rule on the receiving tunnel endpoint (router 2) that causes the receiving endpoint to block advertisements of the source network (192.68.1.0) in its routing updates. This prevents 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 as an illustration, configure the following policy rule on router 2 and activate it on the router RIP with the matching interface:

Accept policy Configure a policy rule on the source tunnel endpoint (router 1) that will cause the source endpoint to not accept routing updates that include the source network (192.68.1.0). This solution is for nested tunneling caused by RIP. For example, using the network shown in Nested tunneling example as an illustration, you would configure the following policy rule on router 1 and activate it on the router RIP with the matching interface:

Static route Configure a static rule on router 1 telling it the route for packets destined to the tunnel’s receiving endpoint (192.68.1.2). This route should be configured with a high route preference. For example:
