問題文
A team writes a local role on a BGP session so that what it announces is passed only to the parties that are meant to receive it. Which reading of that role does the documentation give?
選択肢
- The device sets the attribute from the role and then refuses any session on which the far side wrote the same role as the local one, and it acts on every family that the session carries.
- The device sets the attribute that records where the route came out of by itself from the role, the mode in place unless changed makes the role of the far side mandatory, and it acts on unicast prefixes alone.
- The device sets the attribute from the role, and where a role is written for particular prefixes instead, the policy for that has to be attached to the outgoing direction alone so that the incoming direction is left free.
- The device waits for the operator to write the attribute into a policy of its own, the mode in place unless changed lets a session come up whether or not the far side of the session has sent a role of its own, and it acts on every family that the session carries.
