Re: Netflow on IOS-XR

Sure, nothing specific to his config:

Code: Select all

interface Bundle-Ether1.106
 flow ipv4 monitor Monitor_NAME sampler Sampler_NAME ingress
This is from 6.1, but with 5.3.4 it should be the same.

Re: overrun and packet loss issues

Ihab, 6704 has famously small buffers (16MB). I don't believe with that speeds you can even accomodate buffering/shaping at that level. Better option would be to go with 6708 (200MB of buffers), which would give more space for the card to handle different scheduling/policing requirements on the traf...

Re: Restart MPLS process

Well, you can't in IOS, IOS-XE and NX-OS. In IOS XR you can restart LDP, but the label range allocation is global value set at router boot. There's enhancement however from 5.3.4, 6.1.2 and 7.0 that in IOS XR moves the label ranges dynamically - but I haven't found anything like that for our other O...

Re: DMVPN over MPLS

What is the advantage over layer 2 because with layer 2 the customer hide own routes from service provider Sure, but the cost here is extending L2 over WAN. Which is never a good thing, given L2 has it's own problems - flooding, troubleshooting and (potential for) loops. We're moving away slowly fr...

Re: What is the best protection design?

...and what's the scenario? Ideally - both. In practice, you'll be facing constraints of different kinds. DWDM-level protection is usually 'cheap' when you have enough fiber in the ground. It's on/off thing. IP, IGP or MPLS layer protection is more universal, but usually harder to implement on a wid...

Re: VPLS Loop

You should run SPT or more advantegous features like mLACP (from SP side) and Etherchannel from your side (to two different PEs).

Re: Which Load-balancing design is better?

Running MPLS on 7600/6500 is full of suprises :) Try to take a look at the release notes and then look for old Cisco Live! presentations.

Re: Which Load-balancing design is better?

TL;DR version: So first of all, second option won't work at all - RSVP-TE will send the LSP over single specific path in this setup. If you want to load-balance "in L3", you need two tunnels - one over each of the links. For "L2" load balancing, here are things you may need to consider: For EoMPLS t...
