I am about to refresh an environment with about 40 vPC pairs of Nexus 9K. I am considering using the IPv4 Link Local addressing for the keep alive links: RFC 3927 - 169.254.0.0/16. This is because this range is otherwise unusable and unrouteable. Has...
Has Cisco stopped manufacturing the CAB-1309-C19-INT? This power lead is for the 6000W PSU for a Catalyst 4500 chassis. It has a C19 at the switch end and an IEC309 at the supply end, and is about 4m long. My usual Gold Partner can't get hold of any....
I have a number of ISR 4431s that all droop in the rack, no matter how tightly I do up the rack bolts. This means that they intrude significantly into the space underneath them preventing other kit being mounted there. (this may even be due to the ra...
I have just completed an online Cisco Customer Satisfaction Survey. I answered every question and left some comments in the comment box. Having done that I clicked on submit. I was returned the same screen, pre-filled with all of my responses, asking...

If you get to the point of considering the 4551, it might be worth looking at the ASR920 instead, depending upon your requirements. hope this helps, Dave
Please be careful. If all of your sites use the same AS number, when one boundary router receives an advertisement that contains its own AS in the AS-path, it will reject the route. I would suggest at the very least, you should change your hub AS (or...
If R1 & R3 are not uniquely originating any prefixes into the AS, they do not need to peer. This set of prefixes would even include the routers' own loopback interfaces and any subnets that are local to those two routers only. However, on the assumpt...
Obviously, be aware that this might not be your problem routing out to 192.168.180.0/24, but the remote system may not be able to route back to 192.168.100.0/24 Hope this helps. Dave
