Can you double-hop ISL? Suppose: |cisco | |router|------|Cat 2901|-------|Cat 1900| Can ISL run 'through' the 2901? The Cat 1900 Enterpise can do ISL; what I am asking is can I assign interfaces off of the 1900 to sub-interfaces on the router (ISL then would run through the 2901), and at the same time have other interfaces on the 2901 act in other ISL groups? -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Atheism is a non-prophet organization.
