Good day,
Yes, my 1st post and ask. The questions are Arch - Implementation approach oriented, hence some backgraound .
I'm also wondering should I post this to Datacenter ?
Background
I'm hoping to leverage the expertise I've seen. I'm taking this tactic because JTAC is not answering my questions, labeling it testing and non production oriented.
We've been a Juniper shop for > 12yrs, from v10.x and onward with experience and deployment of many platforms in ex23xx, ex42xx, ex34xx, ex43xx, ex46xx, ex9214, ex9253, qfx35xx, qfx510xx, qfx5120, qfx10008, mx5, mx104, srxx300 ..to srx5600 , etc , using virtual-chassis, vcf[now gone] and clustering.
We 'e deployed a number of mc-lag peers , ex4600 and ex9214, at the distribution/spine layer [L2/L3] of small sites and Campus, and have a feel of most of the niggles, but who knows everthing ;-)
I know I dont.
What
Our legacy datacenter has 2x ex8216s at the dist/spine layer in a traditional L2/L3 config; RSTP disabled, but VSTP used for approx 55 of 85 vlans.
- Several TORs access switches are deployed with uplinks using RTG; when cutover to the planned qfx10K , they would be reconfigured using only 1 aeX to an mc-aeX on the qfx
- Other TORs supports connect in an H pattern hosting VLANs configured with vstp , rooted to say ex8216[1]
- We have a couple EMC/VCE converged compute solutions hosting 95% of our VMware stack, which connect using cisco nx9K, and r-pvstp+ / vlan
The EOL ex8216s have to go... we purchased, built, 2x qfx10008 and deployed them as mc-lag peers.
This is a Bown-field Implementation- cut-over, not Green field so it tricky.
Question:
My integration approach was to use 1 main mc-ae from the qfx10[s] -> to the primary ex8216[1] and extend L2 vlans
Test VSTP integration - rooting, etc.
It does not appear any vlan configured for VSTP on either end of the above mc-ae is converging, or logging rec'vd BPDU.
Neither "The Juniper Multichassis Link Aggregation User Guide" nor any "nce" paper really talk about or show mc-lag peers Also supporting VSTP.
Given how the ICCP/ICP-PL behave, am I going to need "another aeX -trunk between the 2x 10Ks to support the vlans configured for VSTP to alow them to behave ?
This is an operatonal DC, so I cant just re-configure our VCE Converged solutions even though they have A nd B nexus 9ks, etc
Options, thoughts, ? anything is appreciated,
Michael B
