BB3-RACK1(config-router)# redistribute connected metric 2

Task 16.6:
This example represents the same steps for PE1, PE2, and PE3.
Exclude RR from the MPLS/LDP configuration because RR is not in
data-path forwarding.

Enable only the interface facing the SP1 and SP2 core. MPLS/LDP
between ASBRs will be handled by mBGP.
ASBR2-RACK1(config)#int e 0/0
ASBR2-RACK1(config-if)#mpls ip

Task 16.9:
♦ Configure all MPLS traffic flow over ASBR1 S0/0 to ASBR2 S0/0.
♦ Configure such that only MPLS traffic is allowed from ASBR1 to
ASBR2.
♦ Configure SP1 and SP2 such that VPN Solaris site 2 can
communicate with Solaris site 1.
♦ No IGP is allowed between ASBR1 and ASBR2.

♦ MPLS must be dynamically enabled from ASBR1 to ASBR2.
♦ No static routes allowed.
♦ VPN Solaris site 1 (CE1) should ping site 2 (CE6).
♦ VPN Green site 3 (BB3) should ping VPN Green site 1 and VPN
Green site 2.
This task requires configuring ASBR1 and ASBR2 to support InterAS.
This solution will show you how to activate Inter-AS and you will
notice some challenges in PE1 router peering with ASBR1.

This will cause the Route Reflector to not reflect any routes from
SP2 because PE1 is rejecting all routes that arrived from SP2. Let’s
debug and verify why this happens.

This means PE1 is rejecting all communities because PE1 is not
participating in VPN Green and VPN Solaris. To resolve this issue,
we must disable PE1 behavior from examining communities from

other VPNs.

Task 16.10:
♦ Configure CsC on CE8 for SP1 to run over OSPF in area 0.
♦ Configure Csc on CE1 for SP2 to run over OSPF in area 0.
♦ Configure appropriate Loopbacks to meet the CsC requirements.
♦ Configure PE2 in 65001.
♦ Configure PE3 in 65001.
♦ Inject OSPF from CsC CEs in to CsC BGP 65001 cloud.
♦ Verify that CE8 is able to ping the CE2 Loopback and vise-versa.

♦ Prepare CsC-PE2 to CsC-CE8 and CsC-PE3 to CsC-CE2 to
support MPLS/VPN over the CsC cloud.
