Using Esrp With Mpls Tls - Extreme Networks BlackDiamond 6800 MPLS Installation And User Manual

Using ESRP with MPLS TLS

The following commands disable BCP mode and enable POS transparent mode on the
OC-3 interface that is a member of the TLS VLAN:
config ppp bcp off port 1:1
config ppp pos transparent-mode on port 1:1
The following command creates the TLS tunnel to LSR 4 for SONET PPP traffic received
on VLAN sonet:
config mpls add tls-tunnel sonet 11.0.4.11 tls-vlan 8f002 8f005
The SONET configuration for LSR 4 is exactly the same as the configuration for LSR 1,
but the TLS tunnel is targeted towards LSR 1, as follows:
config mpls add tls-tunnel sonet 11.0.1.11 tls-vlan 8f005 8f002

Using ESRP with MPLS TLS

ESRP can be used in conjunction with TLS to provide redundancy. For example,
consider adding a second LSR to the hub, as shown in Figure 7-5.
