Which statement is correct about the inet.3 routing table?
A. MPLS creates a copy of the mpls.0 table and stores it in the inet.3 routing table. B. The inet.3 routing table is used by transit routers to identify label values. C. BGP can use the inet.3 routing table to resolve next hops. D. MPLS uses the inet.3 routing table to assign labels.
Explanation: The IGPs and BGP store their routing information in the inet.0 routing table, the main IP routing table. If the traffic-engineering bgp command is configured, thereby allowing only BGP to use MPLS paths for forwarding traffic, MPLS path information is stored in a separate routing table, inet.3. Only BGP accesses the inet.3 routing table. BGP uses both inet.0 and inet.3 to resolve next-hop addresses. If the traffic-engineering bgp-igp command is configured, thereby allowing the IGPs to use MPLS paths for forwarding traffic, MPLS path information is stored in the inet.0 routing table.
