Sorry guys, to manipulate per nighbro for specific routes you have to use second method
ie: distance 110 neighbor_ip wildcardmask acl#

Hi Chen,

Your are right eigrp has 2 variance of defining admin distance in eigrp.
(1.)distance eigrp xxx 90 170(internal and external)
(2.)ditance 110
Try both in the first command you can change the distance of internal eigrp and external eigrp but not for any specific neighbor and cannot influence by distnace. If you want to manipulate ad per nighbor for specific routes you have to use first method. Try both commands and see.

Hi Mani,

the distance command in EIGRP has the format like this :
distance eigrp internal-distance external-distance
how can this command can be use to influence the distance of a specific route from a specific neighbor?

typically, I gonna use distribute-list to filter specific route in EIGRP.

Hi Ray,

You cannot influence the distance on a neighbor by configuring your router. But you can go to that neighbor router and change the distance. AD only affecting locally on a router. For example you can configure router1(say 10.10.10.1) to have AD of 111 for 200.200.200.0/24 network received from router2(10.10.10.2).
configuration:
==========================
ROUTER1:
access-list 11 permit 200.200.200.0
router eigrp xxx
distance 111 10.10.10.2 0.0.0.0 11
distance xxx neighbor ip wildcardmask access-list (In ospf this neibor ip must be router-id of the router)
==========================
The above commands makes AD of 200.200.200.0 network leaned from 10.10.10.2 neighbor to appear in R1 routing table as 111, so if the same network is leared by ospf too(AD= 110), The router R1 perfers ospf routes over eigrp routes.

thanks

Hello Group,
Can anyone confirm if the eigrp distance command can be applied to a
specific neighbor using an access-list to change one advertised
network? Any help would be great.

TIA
Ray
