In a Hub&Spoke network, the route transfer path of VPN1 is shown in the figure. When Hub-PE forwards the VPN1 route to Spoke PE2, which of the following AS_Path is carried?

An OSPFv3 NSSA LSA is generated by an ASBR, describes routes to a destination outside the AS, and is advertised in an NSSA.

I-SPF and PRC can speed up ISIS route convergence. PRC does not calculate nodes. Instead, it updates routes based on the shortest path tree (SPT) calculated using the SPF algorithm.

MPLS determines the upstream and downstream relationship based on the data forwarding direction. The MPLS label message is sent from the upstream LSR and received and processed by the downstream LSR. Similarly, the release of MPLS labels is also distributed one by one from upstream to downstream.

In a large enterprise network, two border routers R1 and R2 connect to two different ISPs using eBGP. Both routers advertise the same internal network 10.10.10.0/24. The enterprise wants outbound traffic to prefer ISP1, while inbound traffic from the Internet should prefer ISP2 whenever possible. Which configuration combination can achieve this requirement?
