SPAN over IP Routed network

Unanswered Question
Oct 19th, 2007

We have two sites connected via STM1 link on 7200 and 7600 routers. One site is housing Call Center agents and other site with the entire server infrastructure.

Requirement is to send all the SPAN data collected at site A to a recording server on Site B. Can we transfer VLAN info over routed network or any other methods.

I have this problem too.

ERSPAN supports source ports, source VLANs, and destination ports on different routers, which provides remote monitoring of multiple routers across your network ERSPAN consists of an ERSPAN source session, routable ERSPAN GRE-encapsulated traffic, and an ERSPAN destination session. You separately configure ERSPAN source sessions and destination sessions on different routers.

To configure an ERSPAN source session on one router, you associate a set of source ports or VLANs with a destination IP address, ERSPAN ID number, and optionally with a VRF name. To configure an ERSPAN destination session on another router, you associate the destination ports with the source IP address, ERSPAN ID number, and optionally with a VRF name.
