PFA of my Network proposal to customer.
Brief about design :
1. We have two sites , Site A has enterprise data center
Site B has Nexus datacenter for servers
2. Site A have 6500 chasis with VSS configured and Site B has 7k,5k,2k with vPC configured.
3. Site A have two firewalls connected to 6500 VSS pair for internet access
4. Site B have two routers connected for MPLS links , one link is local country and other link to international link.
Now i am preparing for Solution document.
I need your expert assistance on the Following
1. Cat 6500 configured VSS and N7K paired with vPC. I would need to give connectivity between 7K pair to 6500 VSS pair.
I read that with vPC , we cannot make L3 adjacencies with vPCeers then suggest the recommended connectivity between VSS pair and 7K forL3 communication with OSPF routing protcol.
How it load balance the traffic between VSS to 7K devices.?
2. At my datacenter , I have suggested single sided vPC, CAN I MAKE DOULBLE SIDED vPC
MEANS 5k vPC pair and 7k vPC pair same time?
What is the advantages of double sided vPC?
3. 6500 VSS pair connects to 2 firewalls ,what configuration is best at FW high availbility , is active /standby or Active /Active? what is the connectivity between VSS to both firewalls?
It's realy appreciate if you could provide solution so that i can go for solution document.
