Vpc Peering Nexus

In a vpc topology when a receiver is connected to a cisco nexus 5500 platform switch or fabric extender fex via vpc both peer switches initiate a pim s g join toward the source dr.

Vpc peering nexus. Cisco vpc aka virtual port channel which was launched in 2009 is a feature on the cisco nexus series switches that allows end device to configure a port channel across multiple switches.

It is not possible to configure vpc on a pair of switches consisting of a nexus 7000 series and a nexus 5000 series switch.

The vpc peering connection request is awaiting acceptance from the owner of the accepter vpc. If the vpc peer link is configured on a cisco nexus 32 port 1 10 gigabit ethernet f1 series module n7k f132xp 15 you must include the l3 backup routing vlan in the vlan list specified by the peer gateway exclude vlan command. Vpc peer switch.

The vpc peer link is the link used to synchronize states between the vpc peer devices. A vpc peering connection is a networking connection between two vpcs that enables you to route traffic between them using private ipv4 addresses or ipv6 addresses. The failed vpc peering connection remains visible to the requester for 2 hours.

Vpc is not possible between a nexus 5000 and nexus 5500 switches. On the nexus 5000 you can modify the default vpc behaviour when a peer link is down on the primary vpc switch the default behaviour on the primary vpc switch after a peer link goes down is to keep the vpcs down once they get flapped and to not bring up newly configured vpcs. Instances in either vpc can communicate with each other as if they are within the same network.

The vpc peer switch is one of a pair of switches that are connected to the special portchannel known as the vpc peer link. The vpc peer link carries control traffic between two vpc switches and also multicast broadcast data traffic. One device will be selected as the primary device and the other will be the secondary device.
