Combine show ip route vrf and show ip bgp vpnv4 vrf to Confirm Route Installation
A network engineer runs the following command on Router R6:
R6# show ip route vrf CUSTOMER-D
VRF CUSTOMER-D:
10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 10.0.0.0/30 is directly connected, GigabitEthernet0/0.400
L 10.0.0.1/32 is directly connected, GigabitEthernet0/0.400
192.168.0.0/16 is variably subnetted, 1 subnets, 1 mask
B 192.168.1.0/24 [200/0] via 10.0.0.2, 00:10:00

Based on this output, what can be concluded?
Quick Answer
The correct conclusion is that the route 192.168.1.0/24 is installed in the VRF routing table from BGP. This is confirmed by combining the outputs of both commands: the `show ip route vrf CUSTOMER-D` reveals a `B` code for the prefix with an administrative distance of 200, indicating an iBGP-learned route, while the `show ip bgp vpnv4 vrf CUSTOMER-D` output shows the same prefix marked with `*>`, meaning it is both valid and the best path in the BGP table. On the ENCOR 350-401 exam, this scenario tests your ability to verify BGP VPNv4 routes in VRF routing table by cross-referencing the routing table with the BGP table—a critical skill for troubleshooting MPLS Layer 3 VPNs. A common trap is assuming a route is installed just because it appears in BGP; you must check for the `B` code in the VRF routing table to confirm actual installation. Memory tip: think of `show ip route vrf` as the "final destination" and `show ip bgp vpnv4 vrf` as the "candidate list"—only routes with the `B` code in the first command have made the trip.
⚠ Common exam trap
Cisco often tests the distinction between the routing table (show ip route) and the BGP table (show ip bgp), where a route can be present in BGP but not installed in the routing table if the next-hop is unreachable, but here the route is installed, confirming reachability.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The route 192.168.1.0/24 is installed in the VRF routing table from BGP
The show ip bgp vpnv4 vrf CUSTOMER-D output displays a BGP route for 192.168.1.0/24 with the '> ' (best) marker, and the show ip route vrf CUSTOMER-D output shows this route with a 'B' code (BGP). This confirms the route is learned via BGP and installed in the VRF routing table. The administrative distance of 200 in the routing table entry further confirms it is a BGP route (eBGP default AD is 20, but iBGP is 200; the [200/0] indicates iBGP).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The route 192.168.1.0/24 is learned via OSPF
Why it's wrong here
Both outputs show it is BGP (B and BGP table).
- ✓
The route 192.168.1.0/24 is installed in the VRF routing table from BGP
Why this is correct
The VRF route shows B, and the BGP table shows the same prefix with next-hop 10.0.0.2.
- ✗
The next-hop 10.0.0.2 is not reachable
Why it's wrong here
The route is valid and best (*>), indicating reachability.
- ✗
VRF CUSTOMER-D has no directly connected networks
Why it's wrong here
There is a directly connected network 10.0.0.0/30.

Variation 1. A network engineer runs the following command on Router R1: R1# show ip route vrf CUSTOMER-A VRF CUSTOMER-A: Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route Gateway of last resort is 10.0.1.1 to network 0.0.0.0 10.0.0.0/8 is variably subnetted, 3 subnets, 2 masks C 10.0.0.0/30 is directly connected, GigabitEthernet0/0.100 L 10.0.0.1/32 is directly connected, GigabitEthernet0/0.100 B 10.0.2.0/24 [200/0] via 192.168.1.2, 00:12:34 Based on this output, what can be concluded?
medium- ✓ A.VRF CUSTOMER-A has a BGP-learned route to 10.0.2.0/24
- B.VRF CUSTOMER-A is not using BGP for routing
- C.The default route is learned via BGP
- D.GigabitEthernet0/0.100 is not associated with VRF CUSTOMER-A
Why A: The output shows a BGP-learned route to 10.0.2.0/24 with the code 'B' and the administrative distance [200/0], indicating it is an external BGP route. The route is installed in the VRF CUSTOMER-A routing table, confirming that VRF CUSTOMER-A is using BGP and has learned this prefix via BGP from the next-hop 192.168.1.2.
