Need your assistace please regarding below command
R1> show ospf route routerTopology default Route Table:
Prefix Path Route NH Metric NextHop NexthopType Type Type Interface Address/LSP10.0.0.0/24 Intra Router IP 5100 ae10.0 188.8.131.52.0.0.0/24 Intra AS BR IP 5100 ae2.0 184.108.40.206.0.0.0/24 Intra Network IP 5101 ae3.0 220.127.116.1118.104.22.168/32 Ext1 Network IP 1050 ae4.0 22.214.171.124
Intra should be intra (level-1/level-2) LSA and Ext should be level-5 LSA
However what does "Rotuer" , " Network" means ?? It can't be level-1 / level-2 as Ext1 is with Network
Many Thanks for your assistance
First of all, there is no level-1/level-2 in OSPF, only in IS-IS. 🙂
Back to your question:
(1) The Path Type is either Intra (type-1/2 LSAs), Inter (type-3 LSAs) or Ext1/2 (type-5/7 LSAs - depending on the metric type)
(2) The Route type is either AS BR (AS boundary router), Area BR (ABR), Area/AS BR (both ASBR and ABR at the same time), Router (neither an Area BR nor an AS BR), Network which are those prefixes within the type-1 LSAs that have link type 3 (stub network), i.e. all those interfaces that have no OSPF neighbor (= other than p2p or transit).
Thanks Carsten for your reply
For ISIS levels yes it was a mistpe 🙂
One more thing why then Network appears with External (LSA-5) appears ?
