Chapter 1 Viewing MPLS VPNs

VPN Topology Connections

Cisco ANA shows the actual tunnel state (up or down) for the Layer 2 logical link if discovered. The link appears with a minor severity (yellow) when the tunnel is down. Table 1-1shows common MPLS VPN topology map icons.

Table 1-1	Topology
Topology Example		Line	Description
		Solid with arrows at either end.	VPN topology (extranet).
		Solid with arrows at either end.	VPN topology between virtual routers.
		Solid.	Tunnel topology between LCPs.
		Note The link does not reflect a
		status.

Note PE and customer edge (CE) Border Gateway Protocol (BGP) topologies are not supported.

Figure 1-1displays several devices that are connected in a multipath VPN MPLS map in the Cisco ANA PathTracer multipath window.

Table 1-2lists the associations that might appear on the service view map.

Table 1-2 Service View Map Associations

Association Example	Description
	The association between the customer site (IP interface) and the access
	point on the PE.
	The overall connection between the CE device and the site (IP interface),
	which may cross different technologies and layers.
	The overall connection between the CE device and the LCP.
