Internal links between sub-domains

[joycer]

Internal links between sub-domains. Does they effect in the sub-domains ranking some how. Say domain 1 is ranking for some high competitive keywords now if the 1 is linked to 2 then will they pass any link juice.

They will certainly pass some link juice that's for sure.

A search engine considers a subdomain to be a different entity from the root domain and links to and from are considered external.A few links from separate pages may be helpful but engines won't be oblivious to the fact that their coming from the same IP address as the root domain.
