Ok, so here's the scenario I'd like to share with the group.I have an EIGRP enabled router attached to an ASA, which is an EIGRP neighbor. Often, I'll redistribute static routes that are for vpn users and remote sites on the next to last hop before ...
Alright, so just as a sanity check, I've got a question for the group. When configuring the crypto acls that define interesting traffic for a tunnel, are we able to use summaries?So lets say site B is 10.5.10.0/24 and site A can be summarized with 1...
Have a quick design question for the group:Do you personally use loop control mechanisms like bpduguard or storm control on server access switches in the datacenter?Any feedback appreciated,Geoff
Alright, so we're putting together a design for a smaller, green field datacenter and I wanted to reach out to this community for feedback because I've gotten mixed messages about the 4900M platform.A pair of 4900Ms could work as distribution (we're ...
rick - thanks for jumping in, much appreciated. I share your surprise this scenario has presented on 15 line of code peered to an ASA running 8.3 as well as 2 routers in GNS running 12.4 (25)Here's the down stream router I've configured in GNS:!int...
I was in this camp until just a couple of days ago. Run bpduguard on the user blocks only and use change control mechanisms to minimize risk -But we had a network loop created by bridging NICs together on a server and it crushed a pretty critical sw...
Its really a best practices question - the subject of bpduguard in the user blocks is a no brainer - not enabling it is crazy. But I've gotten a range of feedback concerning having it enabled on server access ports in the DC, so I thought I would re...
These will be L3 switches used to aggregate L2 DC access switches (low density). I totally agree with all the comments as far as horsepower - even if there were L3 convergence events, I can't imagine the switches grinding to a halt due to lack of pr...
The Nexus 5000 doesn't currently support layer 3 services - it's hard to tell what the future holds, but right now the 5000 is only layer 2. Even thought its running the 4.1 code, routing won't be available:http://www.cisco.com/en/US/prod/collateral...
