Hi All. I am installing amd64 snapshot from aug 8 on vmware workstation. This VM has 5 interfaces. I have changed them all to use vmxnet3 NIC. vmx0 on openbsd is not ethernet0 in vmware, so are all other interfaces. Any idea how to match the VMware's ethernet NIC order to OpenBSD's NIC's

Re: ospfd filtering

2013-05-01 Thread Dan Shechter
You can't filter OSPF routes inside an area. It will break the OSPF shortest path tree. I don't know about ospfd, but on Cisco IOS you can filter routes (LSAs) between areas and you can also prevent prefixes from being inserted to the routing table of the router where the filtering commands are
