vPC

• vPC virtual port channel, let port's on 2 vPC peers look like they are from one switch, eliminating blocked ports on ethertrunk.
• peer-gateway - only for dumb hosts that do not use arp for gw discovery, but incoming packet.
• pinning max-links 1
• Before the peer link will come up, you also have to set up VPC keepalives to detect dual active peers

  •   vpc domain 1
        peer-keepalive destination 10.10.10.14 source 10.10.10.13

• VPC Rule 101
  • VPC peers are expected to forward a frame received on a member link out any other member link that needs to be used. Only if they cannot do so due to a link failure, is forwarding across the VPC peer link and then out a member link allowed, and even then, the cross-peer-link traffic can only go out the member link that is paired with the member link that is down.
• Restatement of VPC Rule 101
  • To put it another way, VPC peers are expected to forward a frame received on a member link out any other member link that needs to be used. Only if they cannot do so due to a link failure, is forwarding across the VPC peer link and then out a member link allowed, and even then, the cross-peer-link traffic can only go out the member link that is paired with the member link that is down.
