  AS-External-LSA describes the router's path to ASBR

• ○

  The cost value of the second type of external route is only the AS external cost value, ignoring the AS internal cost value

• ○

  AS-External-LSA does not belong in any region

• ○

  AS-External-LSA describes the path to the as outside of the route, and the scope of the flood is the AS outside

• ○

  If As-set is configured, the A S_PATH of the aggregate route contains ass path information for all specific routes in case the route loop is blocked

• ○

  If Suppress-policy is configured, aggregate routes are also generated, and the if-match clause in Route-policy is used to pick suppressed detail routes. Detail routes that match Route-policy are still advertised to other BGP neighbors

• ○

  If Origin-policy is configured, only detail routes that match Route-policy can participate in aggregation

• ○

  If You configure The Interface-policy, you can change the properties of the aggregate route

  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

  Multicast network statically configures RP, while RTA router does not statically configure RP

• ○

  The RP elected by RTA is not an RTB

• ○

  RTB to RTA has no unicast routing, causing the RTB to fail RPF checks for the source

• ○

  The multicast network dynamically elects the RP instead RTA failed RPF check for BSR
