AFAIK adding the network should be the same regardless of technology used. I've always treated a FR/ATM PVC the same as a STM-16 SRP cct. > Ex. for netw. 10.10.10.1/24, would one specify under ospf: > #router ospf 1 > #netw 10.10.10.0 0.0.0.255 area 0 You're adding 10.10.10.0/24 now, example: int fa0/0/0 ip add 10.10.10.254 255.255.255.0 router ospf asn network 10.10.10.0 0.0.0.255 area 0 On some images (at least 12.0S, 12.2, IPv6 EFT) entering router ospf asn network 10.10.10.254 0.0.0.255 area 0 will work the same and actually get translated to the first example above. I don't know how long this has been around but older software seemed to barf on entering the second example above :) > #router ospf 1 > #netw 10.10.10.1 0.0.0.0 area 0 You're adding 10.10.10.1/32. Usually people do this if 10.10.10.1 would be assigned to a /32 loopback interface: int lo0 ip add 10.10.10.1 255.255.255.255 router ospf asn network 10.10.10.1 0.0.0.0 area 0 > Is the network specified or the host address itself. Does it depend if it's > a frame-relay full-mesh (ip ospf network broadcast/non-broadcast) or > partial-mesh (ip ospf network point-to-multipoint) ? It really depends on what your prefix is. Recent versions let you specify "network 10.10.10.126 0.0.0.127 area 0" converting it to "network 10.10.10.0 0.0.0.127 area 0" (ie. the wildcard mask calculates the network address into the config so you just cut-paste the gateway address from "ip address" or somewhere.) If you're buying PtP PVCs between two locations treat it as a /30 or /31 PtP subinterface. If you're buying a mesh, you can always use frame-relay/atm maps on a interface and specify your neighbors explicitly in your ospf configuration. This enables you to assign different costs for each neighbor (for example.) I guess there's at least another way of achieving the above. // kaj Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=62475&t=62463 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
