That might be a bug in translation from NSSA-LSA to Ext-LSA. Could you try if some regular prefix on R3 (e.g. stub network on another iface, not external route exported to OSPF) behave correctly, or behave similarly to the 10.7.100.0/24 prefix? Could you send 'show ospf state' 'show ospf neighbors' and 'show route' on R1 / R2 / R3 for each of these steps (initial, after vlan4001 removal, after ifconfig, after restart R3)? -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santi...@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
