A pair of 6509 with Sup32/MSFC2 connected together via Port-Channel. 802.1Q on port channel. Total VLANs on both switch 8. Total SVIs on both switch 7(one L2 VLAN). I have SVI 1, 11,12,13,21,22,23 on both switches with HSRP.
DR site data center:
A pair of Nexus 5548 with L3 card connected together via Port-Channel/vPC. 802.1Q on port channel. Total VLANs on both switch 4. Total SVIs on both switch 3(one L2 VLAN). I have SVI 10,20,30 on both switches with HSRP.
Connectivity between the data centers:
P2P DS3. When DS3 down, failover to IPSEC VPN.
GRE tunnel created between the 2 data center to achive automated failover over from DS3 to IPSEC.
Stretch VLAN # 1 between both data centers.
1. Single briding with BVIs using GRE tunnel interface and SVI VLAN 1.
2. EoMPLS. Question: Can I do xconnect command to SVI vlan # 1? or xconnect command goes on physical interface only? Would EoMPLS work in my case at all because my DS3 termination is on same device as the switch?
3. L2TPv3. Question: Same as question # 2. Can I do xconnect command on SVI vlan 1 interface?
Currently I need to stretch only 1 VLAN so I can easily get away with option # 1. However I am trying to get to better scalable solution that permits me more VLANs in figure. Any advice?
