Hello Varun
First off, it is not common practice to create a multihop scenario between routers that are so far away. In essence, the number of hops can change at any moment, and will actually be different depending on the path taken between the two routers. In general, it’s a good idea to avoid multihop whenever possible on the Internet. It’s more of a design issue rather than an issue of technical capabilities.
Having said that, it is always possible to set the multihop to a high enough value to encompass all possibilities. You can set it to 50 or even to its maximum of 255 so you won’t have a problem with peering. However, this should be done with great caution as this could open up many security issues. One way to resolve them is to use TTL security which is further described in the following Cisco document:
I hope this has been helpful!
