ASBR Summary
This page displays the OSPF LSA ASBR Summary link state database information table.
An Autonomous System Boundary Router (ASBR) is a router that is running multiple protocols and serves as a
gateway to routers outside the OSPF domain and to those operating with different protocols. The ASBR can
import and translate different protocol routes into OSPF through a process known as ‘redistribution’.
Each page shows up to 999 table entries, selected through the "entries per page" input field. When first visited,
the web page will show the beginning entries of this table.
