Importing a Selected Subset of OSPF-ASE Routes

1.Create a OSPF import source so that only routes that have a tag of 100 are considered for importation.

ip-router policy create ospf-import-source ospfImpSrct100 tag 100

2.Create the Import-Policy importing all OSPF ASE routes with a tag of 100 except the default ASE route.

ip-router policy import source ospfImpSrct100 network all ip-router policy import source ospfImpSrct100 network default restrict
