OSPFv3 and OSPFv2 use a similar set of LSAs, with some differences. Table 21-2 lists the OSPFv3 LSAs, including the LSA function code, which indicates the function of the LSA. Table 21-2. OSPFv3 LSAs Note The LSA link-state (LS) type is created by concatenating 0x200 with the LSA function code. For example, LSA function code 1 has an LS type 0x2001. LSA types 1 and 2 no longer contain route prefixes; instead, they contai..

How is the telephone system similar to the postal and highway systems? The answer to this question can be found by reviewing the properties of the first two systems we examined to see if similarities with the phone system exist. The first property the postal and highway systems have in common is a routable address. The second common property of these systems is a multiple part routable address that can be used to scale the system as the system grows. A routable address has a ..
Configuring SDLC for Multidrop Connections
SDLC supports multidrop connections. These are serial links that connect to several downstream devices in series. Each device has its own SDLC address, which must be configured in the router. The global DLSw configuration for this example is omitted here because it is identical to the previous example: dlsw-branch#configure terminal Enter configuration commands, one per line. End with CNTL/Z. dlsw-branch(config)#interface Serial1 dlsw-branch(config-if)#description Conn..
To participate in a VTP management domain, each switch must be configured to operate in one of several modes. The VTP mode determines how the switch processes and advertises VTP information. You can use the following modes: ■ Server mode—VTP servers have full control over VLAN creation and modification for their domains. All VTP information is advertised to other switches in the domain, while all received VTP information is synchronized with the other switches. By d..
