Hello all,When I create a VRF on a router or L3 switch, am I creating just a separate routing table (like just a separate dictionary of routes), or am I creating an actual new routing process on the box ? So often in diagrams I will see VRF's represe...

Hello all,I've always heard that EIGRP can't handle a lot of routes (like you don't want to blindly redistribute BGP into EIGRP as it could crash the EIGRP process), but I've never heard specifically why that is the case? Is it maybe because of:How E...

Hello all,I'm curious if anyone knows a way to upgrade a Cisco APIC via .iso on a USB drive, say if I got a new APIC in and I need to upgrade/downgrade its OS version before swapping it into the APIC cluster? Would be nice to be able to do this via U...

@Joseph W. Doherty thank you! So kind of like @Giuseppe Larosa 's response, a VRF is a "sort-of" virtual router, in that it has its own routing/ARP table and IP daemon (i.e. virtual L3 environment as you said), but not a "full-blown" virtual router ...

Thank you all for your responses!@Giuseppe Larosa that is interesting about the ISP using OSPF for 50k+ routes, and how the control plane was fine but some platforms experienced storage limitations on the TCAM chips (makes sense with that many routes...

@a12288 funny, that's the procedure I used as well :- ) I was just curious if it could also be done via USB, which could be useful in a Disaster scenario or other situations where network connectivity is slow or outright unavailable. Thanks!

Great article. The pictures don't load for me for some reason, so I had a bit of trouble figuring out what my USB drive was called in the UCS boot menu, so pasting this here so myself and others can reference it later if needed. On my C225-M6 (APIC-L...

Wow, right after I post this I found the answer LOL - I thought hmm I have Interface Selector policies applied to this Port 31 interface, I wonder if I need to remove those first, and yep that was it :- D So if you need to convert a port to a Downlin...
