We have an EIGRP network that we need to connect to a 3rd party. We've agreed that the 3rd Party will join our EIRGP AS so we can swap dynamic routes, however, I want to filter the routes they send to be absolutely sure we don't recevie any unauthorised routes if they
inadvertently make a config mistake.
I know I can apply an inboud distribute list, however, I suspect this would apply to the whole EIGRP process. As there are only really 2 routes that I need to receive from the 3rd party network I was hoping that I could apply a distribute list that only applies to the 3rd party router (ie, appy the distribute list to the ethernet interface which connects to the 3rd party network).
Is this possible?? Or is there a better alternative?? (I've considered redistributing to another protocol or EIGRP AS but would like to avoid this if possible).
Any help greatfully received.
Do you have access to the router to see if you can apply the filter inbound per neighbor?
router eigrp 1
neighbor 192.168.1.1 Ethernet 0/0 distribute-list test in
If not then you would need to do it per vrf/address family
