Reading Assignments • Doyle, pages 192-209, 216-221 (RIP chapter) • Doyle, chapter 7 (RIP v2) • Avaya IP Addressing Tutorial • Avaya VLAN Tutorial (through slide 36) • (Avaya tutorials on “useful links” page
Classless Routing Protocols • End of “class A” “class B” “class C” • RIP v2, OSPF, BGP • Cisco commands • ip classless • ip subnet-zero
Classless Routing Protocols • Every network address (route) must have a mask associated with it, so the masks are advertised along with the networks • For the RIP v1 case, there was room to include a mask in the RIP v2 advertisements with only a little change to the overall format
Variable Length Subnet Masks • Every network has a mask, so no need for the mask lengths to have equal length. • 128.186.121.0 /25 • 128.186.121.128 /30 • 128.186.121.132 /30 • 128.186.121.136 /29 • Think in bits!! 128.186.121.132 /29 is an incorrect network. Do the math.

VLSM example • Review Figure 7.4 and table 7.1 in Doyle, pp 289-290. Expect a quiz on a similar network sometime. • Example: You must connect 2 networks in Tallahassee with 2 networks in Jacksonville. The TLH nets need to support 25 hosts each, JAX nets, 5 and 10 hosts • You may use only 128.186.1.0 /24
