However, unlike IGPs, the BGP autosummary router subcommand causes BGP to summarize only those routes injected due to redistribution on that router. BGP au...

Integrated IS-IS NBMA Design Solutions

Designing IS-IS networks across NBMA WANs is not as straightforward as designing other protocols, such as EIGRP, because IS-IS does not explicitly support NBMA. On the other hand, IS-IS over NBMA is not as complicated as OSPF either.  In the good old days, most organizations had a broadcast...

Mitigating the Detrimental Effects of the BGP Restart

To sum up the earlier discussion, BGP restart causes route flaps, which can lead to transient black holes and increased consumption of link bandwidth and control processor resources. Thus route flaps can degrade the overall network performance. The source of route flaps can be traced back to the ...

Defining Per Port Privileges

To configure the privilege level of a particular line, use the following configuration command: Router1#configure terminal Enter configuration commands, one per line.  End with CNTL/Z. Router1(config)#line aux 0 Router1(config-line)#privilege level 5 Router1(config-line)#exit Router1(c...
