Using the default-information originate Command
OSPF does not support redistribution of statically defined default routes. Instead, OSPF requires the default-information originate router subcommand, which essentially tells OSPF tore distribute any default routes found in the routing table, either static routes or routes from another routing protocol. The following list summarizes the default routing features when using the default-information originate command with OSPF: ■ Redistributes any default route (0.0.0.0/0) in ..
Next-Generation Internet Initiative
The federally funded Next-Generation Internet (NGI) Initiative[] is a multiagency U.S. federal research and development program that is developing advanced network technologies and revolutionary applications and demonstrating these capabilities on testbeds that are 100 to 1,000 times faster end-to-end than today's Internet. The NGI initiative began October 1, 1997, with the following participating agencies: • DARPA (Defense Advanced Research Projects Agency) • DoE (Depa..
Examining the RP’s Multicast Routing Table
In the current state of the ongoing example, as last shown in Figure 20-16, the RP (R3) has joined the SPT for source 10.1.1.10, group 228.8.8.8. The RP also is the root of the shared tree for group 228.8.8.8. Example 20-9 shows both entries in R3’s multicast route table. Example 20-9 Multicast Route Table Entry for the Group 228.8.8.8 for R3 The first entry shows the shared tree, as indicated by the S flag. Notice the incoming interface is Null because R3, as RP, i..
RSVP-TE Control-Plane and Forwarding-Plane Components
Now that the usage of RSVP-TE in MPLS-TE has been reviewed, focus turns to the main topic of this chapter: the RSVP-TE control-plane restart. In this chapter, the term FEC refers to an aggregate of data flows defined in terms of filters such as source IP address and other fields in the packet header. Each LSP tunnel is associated with a FEC that specifies which particular set of packets is to be mapped onto the LSP tunnel. RSVP-TE is used to create both resource reservations ..
The finger command is a simple utility that allows you to do the equivalent of a show users command on a remote router. Unix computers generally have a standard finger program that you can run as follows: Freebsd% finger @Router1[Router1] Line User Host(s) Idle Location ..
