A、No action required, wide metrics are used by default in IS-IS. B、Enable wide-metrics-only under protocols IS-IS. C、Enable traffic-engineering under protocols IS-IS. D、Disable TLVs 2 and 128 which carry the 6-bit metrics (0-63).
A、When summarization is configured, the router will also create a route to null 0. B、The summary route remains in the route table, even if there are no more specific routes to the network. C、Summarization is configured on a per- interface level. D、The maximum metric for the specific routes is used as the metric for the summary route. E、Automatic summarization across major network boundaries is enabled by default.
A、Master,or person in charge B、Chief Engineer,or engineer in charge if no chief engineer is required C、Senior mechanic,or mechanic on duty if no senior mechanic designated D、Senior electrician,or electrician on duty if no senior electrician designated
A、A. If using IS-IS as the PE-CE routing protocol, no redistribution is required. B、B. If using static routes between the CE and PE routers, no redistribution of other VPN routes is required. C、C. If the PE-CE protocol is not BGP, redistribution of other VPN routes from MP-BGP is required. D、D. If RIP is the routing protocol that is used between the PE-CE routers, no redistribution is required, but any other protocol will require redistribution. E、E. If using OSPF or EIGRP as the PE-CE routing protocol, redistribution is not required, but any other protocol or static route will require redistribution.
