OSPF processing on a Sidewinder G2 Figure C-2. OSPF areas OSPF processing on a Sidewinder G2 C-4 Configuring Dynamic Routing with OSPF Take a look at a sample configuration. Figure C-2 shows a large internal network and backbone terminating at a router. area 0 (backbone) Complicated Network Autonomous system (AS) R ABR area n (8.8.8.8) Complicated Network Stub areas are areas where there is a single exit point. An OSPF router sends "summary" LSAs into the stub that point back to that router as the default router for the stub area. For more information on OSPF and Internet routing, check with your router vendor. The following books may also be useful: Routing in the Internet, 2nd edition by Christian Huitema, Prentice Hall (2000) Cisco Router OSPF: Design and Implementation Guide, by William R. Parkhurst (Cisco Technical Expert), McGraw Hill (1998) OSPF processing is done via a Sidewinder G2 server process called gated. To implement OSPF processing on the Sidewinder G2, a gated server process must be configured, enabled, and started in the burb expecting to handle OSPF broadcasts. Only one gated may be started per burb, but that gated will handle all network interfaces within that burb. The Sidewinder G2 currently runs version 3.6 of gated. This is the most recent freely available version of gated available from the OSPF Consortium and it's successor, NextHop. This release of OSPF on the Sidewinder G2 runs gated as an "intraarea" router. That means all interfaces that are configured to run OSPF exist in the same OSPF area. Note: Support for the Sidewinder G2 running as an ABR will come in a future release. R ASBR EGP BGP
Figure C-3. Sidewinder G2 within OSPF area 0 backbone Figure C-4. Sidewinder G2 within OSPF area "n" OSPF processing on a Sidewinder G2 Sidewinder G2 in an OSPF network topology Essentially there are two choices for locating the Sidewinder G2 within the OSPF network topology. the Sidewinder G2 within OSPF area 0 backbone the Sidewinder G2 within OSPF area n The first choice, shown in Figure C-3, extends the AS backbone through the Sidewinder G2. Any area boundary external is to the Sidewinder G2. area 0 (backbone) Complicated Network Autonomous system (AS) R ABR area n (8.8.8.8) Network R ASBR The second choice, shown in Figure C-4, runs a non-backbone area through the Sidewinder G2, placing the backbone completely internal. This second option is preferable for security policy reasons, but may not be practical without re-engineering the OSPF network. area 0 (backbone) Complicated Network b u r b b u r b Sidewinder G2 Autonomous system (AS) R ABR b u r b area n (8.8.8.8) b u r b Sidewinder G2 ASBR Configuring Dynamic Routing with OSPF C-5 R
