DIS generate pseudonodes and pseudonodes LSP. Pseudonodes build the neighbor to other isis routers include DIS, like the DR function in OSPF, pseudonodes is used for saving the ISIS database synchronous entrys and reducing flooding, so I think this mechnism can have a good performance in cpu and routing table resourse.
However, in P2P ISIS network ISIS LSA run on a different way,
So My problem comes out:
Pseudonodes is not the real router but it will occupy extra LSP item！
A network IGP is constructed upon ISIS broadcast way, if I change the router-router isis neighbor link to p2p mode, will I get a better convergence
time, isis database saving or cpu resource。And if I do this， what happend to the ISIS like isis neighbor down then rebuild or other fault?
Hi, everyone When I run a simulation of uRPF loose mode on the GNS3, I found that the suppressed verification counter increased.And from the document,https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/sec_data_urpf/configuration/xe-3s/sec-data-urpf-xe...
Before the upgrade, I was able to SSH into a level 15 user and it would land me directly to # without using enable. After upgrading to from 16.3.8 to 16.9.4, my level 2 account can still SSH in but level 15 user account gets % login invalid. So I try...
What design is generally recommended for an office with approx 400 client devices. We have about 10 x access L2 switches (2960x) and are not sure whether to go with 1 x L3 stack (4 x 9300 switches) or maybe 2 x stacks (of 2 x 9300 switches). We are thinki...
After I create a VLAN i can no longer access the GUI.port 1 - trunk connected to routerport 2 - access, PCThe switch is connected to an Edgerouter.I'm sure it's something simple, but I'm new to VLANs and can't figure it out.
