In-Depth Information
In Figure 10-7 and subsequent figures in this chapter, solid boxes are used to contain the
advertisement of IPv4 prefixes and labels, and dashed boxes are used for the advertisement
of VPNv4 prefixes and labels.
NOTE
The relevant configurations on PE2 are shown in Example 10-11. Note that a static route
within VPNa is created with the next hop set to CE2.
