I have a small query for you guys:
1). I have two 6509s and wants dual interconnectivity between them. What would be the best solution; L2 Etherchannel or L3 Etherchannel or L3 routed links?
2). Both switches have SUP720 and 10G modules. What shall I use to to get dualconnectivity. Both 10G ports on SUP card or one from each i.e. SUP and 10G card.
3). If I go ahead for dual connectivity with One port from SUP and another from 10G card. Can I still use other 10G port on SUP card to connect my distribution layer stack to it?
Thanks in advance.
