Your Path to Success: How to Pass the Nokia 4A0-106 Nokia Virtual Private Routed Networks Exam

MP-iBGP sessions must be configured between the PE routers in each AS.

LDP must be configured in each AS.

MP-eBGP sessions must be configured between the ASBRs.

The ASBRs must be configured with "enable-inter-as-vpn".

MP-BGP for exchanging customer routes with other PEs.

A routing protocol for exchanging customer routes with the CE.

A label signaling protocol for defining transport tunnels between the PE and CE.

MPLS for exchanging labels with other provider core devices.

CE1

PE2

PE1

CE2

The route with the shortest AS path.

The route with the lowest route or tunnel table cost to the NEXT_HOP.

The route with the highest local preference.

The route with the lowest originator ID or BGP identifier.

PE1 advertises 64496:1:192.168.1.0/27 route update to ASBR1.

PE2 advertises 192.168.1.0/27 route update to CE2.

ASBR1 advertises 64496:1:192.168.1.0/27 route update to ASBR2.

ASBR2 advertises 64497:1:192.168.1.0/27 route update to PE2.

The route distinguisher of the VPRN on the local PE must be different from the route distinguisher of the remote PEs.

ecmp must be configured within the VPRN instance.

eibgp-loadbalance must be configured within the VPRN instance.

ibgp-multipath must be configured within the VPRN instance.

Each PE must implement a policy to apply a unique SoO attribute to the set of routes received from each customer site.

A different BGP extended community is used on each PE that connects to a single site.

An import policy on the PE rejects a route if the attached SoO matches the configured value.

Import and export policies are applied on the PEs under the global BGP context.

MP-iBGP is used between PE1 and ASBR1 to exchange VPN-IPv4 routes.

eBGP is used between ASBR1 and ASBR2 to exchange IPv4 routes.

MP-eBGP is used between PE1 and PE2 to exchange VPN-IPv4 routes.

MP-eBGP is used between ASBR1 and ASBR2 to exchange labeled IPv4 routes.
