L2 Vpn Design; Figure 3: Example Of L2 Vpn, Vlan-Id 12 Dropped Off At Sites 2,3 & 5 - Avaya 8600 Technical Configuration Manual

The VRF and IPVPN functionalities used in this design requires the use of ERS 8600 R

or RS I/O Modules, 8692SF/CPU fitted with Super-Mezzanine daughter card, Premium
Software License and Software 5.0 or higher.

L2 VPN services will be provided by creating native VLANs on top of the SMLT design; these VLANs will
not have an IP assigned and can be added/dropped at any site. A suitable range of Vlan-ids will be
reserved for these L2 VLANs; in this configuration guide Vlan-ids 2-99 are reserved for this purpose. As
illustrated in Figure 3, Vlan-id 12 is spanned across 3 sites. Please note that any of these L2 VLANs must
always be configured on both Main Sites 1 & 2 (SMLT IST cluster) and only on the ERS 8600 SMLT edge
switches that require the VLAN(s). Pertaining to figure 3 above, L2 VLAN 12 must be added to the SMLT
IST cluster switches at sites 1 and 2 and then added at Sites 3 and 5. At sites 2, 3 and 5, L2 VLAN 12 will
also be configured on one or more edge facing interfaces.
