Does anyone have any idea how to filter out LSA updates between areas? I am
using the Cisco 7204 VXR routers as ABRs and Enterasys routers as ASBRs.
However, I do not want routes to be propagated from the backbone area to any
other area. The limitation is that the Enterasys gear we are using does not
support NSSAs.
Regards,
Simon Rizkalla
