Configure the multi-role host feature.
4.
You can configure a static route between CE 2 and PE 1 or use a routing protocol. To use a routing
protocol between CE 2 and PE 1, configure PE 1 to not advertise any routes to CE 2 to avoid
routing loop.
The following example shows how to use static routes to configure the multi-role host feature:
# On CE 2, create a default route to PE 1.
[CE2] ip route-static 0.0.0.0 0.0.0.0 20.1.1.2
# Create a multi-role host route on PE 1.
[PE1] ip route-static vpn-instance vpn1 172.16.0.0 16 vpn-instance vpn2 20.1.1.1
# Redistribute routes of VPN 1 to VPN 2 through the RT attribute.
[PE1] ip vpn-instance vpn2
