There are two Communily filters: ip comimuniy-lite lpemit 101201 ip community fiter 2permit101 ip commmuriyfilter 2pemit21 Regarding the above ommuniyfiter, the correct description is ?( Multiple choice questions).

As long as the group attribute value carried in the BGP route contains 100:1 or 200:1, or both, the BGP route matches the community-filterl

As long as the group attribute value carried in the BGP route contains 100:1 or 200:1, or both, the BGP route matches community-filter2

The BGP route matches community-filter 1 only if the community attribute values carried in the BGP route contain 100:1 and 200:1

A BGP route matches community-filter2 only if the group attribute values carried in the BGP route include 100:1 and 200:1
