Configuring BGP-based auto-discovery for VPLS
It is recommended that the user performs the configuration tasks in the order listed in Table 144 .
Performing the tasks in the recommended sequence minimizes CPU consumption and route
flapping. Except where noted as “optional”, the configuration tasks in the table are required for
VPLS auto-discovery.
TABLE 144 Configuration tasks for VPLS auto-discovery
Configuration task See...
1 Configure a loopback address “Configuring a loopback interface” on page 762
2 Enable BGP4 and assign a local Autonomous System
(AS) number “Configuring BGP4 to support VPLS auto-discovery”
on page 764
3 Enable MPLS and configure LDP To configure MPLS, refer to the Chapter 1,
“Configuring MPLS Traffic Engineering” .
To configure LDP, refer to the Chapter 2, “Configuring
Label Distribution Protocol (LDP)” .
4 Configure VPLS:
•
Create a VPLS instance
•
Define the route target (optional)
•
Enable load balancing (optional)
“Configuring VPLS to support auto-discovery” on
page 766
5 Enable VPLS auto-discovery “Enabling VPLS auto-discovery” on page 769
6 Configure the L2VPN VPLS address family and
activate BGP4 peering “Configuring the L2VPN VPLS address family and
activating the BGP4 peering session”
on page 770
After performing the configuration steps listed in Table 144 , the user can observe the L2VPN VPLS
address family routes, neighbor summary, and VPLS auto-discovery peering. Refer to “Displaying
VPLS auto-discovery information” on page 775.
NOTE
This behavior does not apply to Brocade NetIron CES or Brocade NetIron CER devices when the IPv6
packet has the following format IPv6 header + IPv6 Hop-by-Hop Extension Header + IPv6 Routing
Header (with type 0).
Configuring a loopback interface
The user must configure a loopback address on the Brocade device before enabling VPLS
auto-discovery.
This section contains the following topics:
• “About loopback interfaces and the router ID”
• “Changes that occur when a loopback interface is deleted”
• “Adding a loopback interface”
• “Viewing the loopback Interface”
