10.8.4 Example Scenario
This is an example scenario for using BGP on the Zyxel Device.
10.8.4.1 Scenario: CE - PE (MLPS)
In this scenario, you want to transmit BGP packets from a
CE
router (Zyxel Device) to a peer BGP
PE
router in an
MPLS
network.
•
CE
: The Zyxel Device is the customer edge router located on the customer premises and connects to
a PE router in the service provider MPLS network.
•
PE
: The provider edge router is located at the edge of the service provider MPLS network.
•
MPLS:
MultiProtocol Label Switching (MPLS) forwards data from one network node to the next based
on path labels rather than network addresses.
Update Source
Use this to allow BGP sessions use the selected interface for TCP connections.
• Choose
Gateway
and then enter the gateway IP address
• Choose
Interface
and then select a Zyxel Device interface.
• Choose
None
to use the closest interface.
MDS authentication
key
Type the default password for MD5 authentication of communication between the Zyxel
Device and the peer BGP router. The password can consist of alphanumeric characters
and the underscore, and it can be up to 16 characters long.
Weight
Specify a weight value for all routes learned from this peer BGP router in the specified
network. The route with the highest weight gets preference.
Keepalive Time
Keepalive messages are sent by the Zyxel Device to a peer BGP router to inform it that
the BGP connection between the two is still active. The
Keepalive Time
is the interval
between each Keepalive message sent by the Zyxel Device. We recommend
Keepalive
Time
is 1/3 of the
Hold Time
time.
Hold Time
This is the maximum time the Zyxel Device waits to receive a Keepalive message from a
peer BGP router before it declares that the peer BGP router is dead.
Hold Time
must be
greater than the
Keepalive Time
.
Maximum Prefix
A prefix is a network address (IP/subnet mask) that a BGP router can reach and that it
shares with its neighbors. Set the maximum number, from 1 to 4294967295, of prefixes that
can be received from a neighbor. This limits the number of prefixes that the Zyxel Device
is allowed to receive from a neighbor. If extra prefixes are received, the Zyxel Device
ends the connection with the peer BGP router. You need to edit the peer BGP router
configuration to bring the connection back.
