B . When PE2 receives the same Domain ID as the local BGP route sent by PE1, PE2 will generate Type3 LSA for Type1 LSA and Type2 LSA
C . When PE2 receives the same Domain ID as the local BGP route sent by PE1, for Type3 LSA, PE2 will generate Type5 LSA
D . The Domain ID configured by PE1 can be used as an extended community attribute of BGP and sent along with the route to PE2.
