A、The i su 10.1.0.0/23 route is a suppressed route. B、The i su 10.1. 0.0/23 route is a summary route. C、The i su 10.1.0.0/23 route is an IS - IS external route. D、The R1 IS - IS router is an ASBR. E、The R1 IS - IS router is an ABR that belongs to multiple IS - IS areas. F、The R1 IS - IS router is performing route aggregation and is suppressing the more specific 10.1.0.0/23 prefix.
A、A.Interfaces have a default metric of 1. B、B.Level 1 is intra - area and level 2 is interarea. C、C.Level 1 routing is between an end system (ES) and IS while Level 2 routing is between an IS and IS. D、D. Hosts send ISHs while routers send ESHs. E、E. IS - IS is an open standard. F、F. Metrics depend on interface speed.
A、Based on the default timers, OSPF d etects a failure faster than IS - IS does. B、OSPF default timers permit more tuning than IS - IS does. C、IS - IS is more efficient than OSPF in the use of CPU resources. D、OSPF is more scalable than IS - IS because of its ability to identify normal, stub, an d NSSA areas. E、IS - IS and OSPF are both Open Standard, link - state routing protocols which support VLSM.
