11.8 BGP (Border Gateway Protocol)
The Zyxel Device supports eBGP (exterior Border Gate Protocol) to route IPv4 traffic between routers in
different Autonomous Systems (AS). An AS number is a number from 1 to 4294967295), that identifies an
autonomous system. 4200000000 – 4294967294 are private AS numbers.
See Section 11.7 on page 420 for more information on autonomous systems.

LABEL DESCRIPTION
Peer Router ID Enter the 32-bit ID (in IP address format) of the other ABR in the virtual link.
Authentication Select the authentication method the virtual link uses. This authentication protects the
integrity, but not the confidentiality, of routing updates.
For OSPF, the Zyxel Device supports a default authentication type by area. If you want to
use this default in an interface or virtual link, you set the associated Authentication Type
field to Same as Area. As a result, you only have to update the authentication information
for the area to update the authentication type used by these interfaces and virtual links.
Alternatively, you can override the default in any interface or virtual link by selecting a
specific authentication method. Please see the respective interface sections for more
information.
None uses no authentication.
Text uses a plain text password that is sent over the network (not very secure).
MD5 uses an MD5 password and authentication ID (most secure).
Same as Area has the virtual link also use the Authentication settings above.

MD5 Authentication
