IMPORTANT!
Enabling or disabling the firewall will reset – but not disable – the BFA protection mechanism, if

hosts are actively attacking at the time, this could result in reduced system performance.
1. Change the mode to Edit Private or Edit Exclusive.
2. Navigate to security » firewall. The Firewall Configuration form appears.

Managing IS-IS
Intermediate System - Intermediate System (IS-IS) is one of a suite of routing protocols tasked with sharing
routing information between routers. The job of the router is to enable the efficient movement of data over
sometimes complex networks. Routing protocols are designed to share routing information across these networks
and use sophisticated algorithms to decide the shortest route for the information to travel from point A to point B.
One of the first link-state routing protocols was IS-IS developed in 1986 and later published in 1987 by ISO as
ISO/IEC 10589. It was later republished as an IETF standard (RFC 1142 [http://tools.ietf.org/html/rfc1142]).
IS-IS is an Interior Gateway Protocol (IGP) meant to exchange information between Autonomous Systems (AS).
It is designed to operate within an administrative domain or network using link-state information to decide optimal
data packet routing, similar to OSPF. IS-IS floods the network with link-state information and builds a database of
