Hello.
As I can see the topic of hardware requirements for VPLS has been discussed here many times. Could anyone provide me with links to relevant documentation on it? I am especially interested in description of ES20 card for 7600 router as a card that must face the core of the network. I have been exploring cisco.com and googling for a few days but could not find any docs describing that ES20 facing core network is absolutely necessary. Only a couple of mentions on some forums.
Thank you in advance.
