Linking ESRP Switches

When considering system design using ESRP, we recommend using a direct link.

Direct links between ESRP switches are useful under the following conditions:

Direct links may contain a router-to-router VLAN, along with other VLANs participating in an ESRP domain. If multiple VLANs are used on the direct links, use 802.1Q tagging. The direct links may be aggregated into a load-shared group, if desired. If multiple ESRP domains share a host port, each VLAN must be in a different ESRP group.
