Martin,

This applies to dyamic routing.

If routing protocol is configured  between devices A and B , the
routes/routing table will be exchanged. This routing information
received( by the device) from peer /neigbour devices will used to
determine the best route to the destination IPs. Since the routing
updates received from peer /neigbour will determine the path, its
important to make sure that we only receive routes from legitimate
devices.

 We should configure the devices to validate identity and routing
updates.  It is recommended to configure 1) Authentication 2)
External route filters on ASBRs

Hope this helps.

Thanks,

Hi All

I've always heard as best practice that you should keep your internal
routes off external facing routers.  And I've also heard that it's
possible to get routes from a router/firewall facing the public domain
without having to login to it.  Can anybody explain (or give an
example) of how this is achieved ?  Is it by using ICMP ?  Does this
only apply to routers using dynamic routing or does it also apply to
static routes ?

Thanks in advance !
