Suppose your virtual-router profile has to be applied on both layer3 interfaces you can do the following configuration in command line.
Today my friend asked me why he could not see all the vlans available in IS-IS when he issued show ip route isis command. When I saw it, it turned out that there are four paths leading to the same … Continue reading
Split horizon Split horizon rule is to prevent routing loop. In iBGP a router which learns prefixes from a BGP speaker will not advertise to BGP speaker, this makes a full mesh iBGP peering necessary in order for other BGP … Continue reading
Conditions to form IS-IS adjacency 1. MTU must match. 2. IS level must match. Level 1 and level 1 router can form adjacency, level 1 router can form adjacency with level1/2 router this is because this router has two IS … Continue reading
Acknowledgement Without MR.Keith Barker’s 21 minutes video instruction, constructing MPLS VPN lab will take a longer time. His 21 minutes video instruction summarizes all. MR. Keith Barker has amazing skills to translate complicated concepts into simpler and easier to understand … Continue reading
The diagram is complicated with an additional link, and instead of full BGP route in AS65000, the BGP route is propagated with the help of OSPF. In previous lab, the BGP full mesh was established by peering both subnets of … Continue reading
Using the same network diagram, I would want prefix 10.20.0.0 to be filtered from advertisement by the border iBGP routers (r1 and r3). Using prefix-list is a more granular method than using ACL with distribute-list. Hide r2 prefixes from r5 … Continue reading
