Routing

I was using advertise-best-external on ASRs to speed up convergence time. My topology is likeAS 123: Nexus1 --- Nexus2         |            |AS 456: ASR1   ---   ASR2Nexus 1 only sees ASR's routes through the link (BGP peering) on the left side becau...

Hi,Im about to implement a Policy Based Routing in a complex environment.I'm a little bit frustrated with the monitoring possibilites, which can be applied on a route-map for policy based Routing. I've attached a picture, to explain my problem a litt...

I have a Router R5 who is connected to a Layer2 Switch. Over this Layer2 Switch R5 builds neighborships to two other OSPF-enabled Router; R1 and R2. So R5 has two OSPF neighbors behind the same interface: R5#sh ip ospf neighborNeighbor ID Pri State ...

I have a PPPoE server on the router. The PPPoE client (adsl-modem in my case) recive an IP-address (real IP assigned by ISP) from the Radius server. The Client works well, the laptop attached to the adsl-modem have an access to the Internet. But I ca...
