Remote Mirroring Using Layer 3

To use remote mirroring using Layer 3, enable IPv4 forwarding along the routed path to the device collecting GRE-encapsulated mirrored packets, also known as ERSPAN. Then, configure the collector device's IP address as the remote IP address in the following command:

enable mirror {mirror_name} to remote-ip remote_ip_address {{vr} vr_name} {priority priority_value} {from [source_ip_address | auto-source-ip]} {ping-check [on | off]}]

To configure the GRE protocol type, use the command:

configure mirror to remote-ip protocol-type [erspan-v1 | trans-ether-bridging | user-defined protocol_value]
