Hi! Why I can't see the route from CE on PE in VPN_CUST_B?
PE: ip vrf VPN_CUST_A rd 1:1 route-target export 100:100 route-target import 100:100 ! ip vrf VPN_CUST_B rd 2:2 route-target export 200:200 route-target import 200:200 ! interface Loopback0 ip address 2.2.2.2 255.255.255.255 ! interface GigabitEthernet0/0 ip address 192.168.12.2 255.255.255.0 duplex auto speed auto media-type rj45 mpls ip ! interface GigabitEthernet0/1 ip vrf forwarding VPN_CUST_A ip address 172.16.24.1 255.255.255.0 duplex auto speed auto media-type rj45 ! interface GigabitEthernet0/2 ip vrf forwarding VPN_CUST_B ip address 172.16.25.1 255.255.255.0 duplex auto speed auto media-type rj45 ! router eigrp 1 ! address-family ipv4 vrf VPN_CUST_B autonomous-system 100 redistribute bgp 123 metric 1 1 1 1 1 exit-address-family ! router ospf 100 network 2.2.2.2 0.0.0.0 area 0 network 192.168.12.0 0.0.0.255 area 0 ! router rip ! address-family ipv4 vrf VPN_CUST_A redistribute bgp 123 metric 4 network 172.16.0.0 no auto-summary version 2 exit-address-family ! router bgp 123 bgp log-neighbor-changes no bgp default ipv4-unicast neighbor 3.3.3.3 remote-as 123 neighbor 3.3.3.3 update-source Loopback0 ! address-family ipv4 exit-address-family ! address-family vpnv4 neighbor 3.3.3.3 activate neighbor 3.3.3.3 send-community extended exit-address-family ! address-family ipv4 vrf VPN_CUST_A redistribute rip exit-address-family ! address-family ipv4 vrf VPN_CUST_B redistribute eigrp 100 exit-address-family Router#show ip route vrf VPN_CUST_B Routing Table: VPN_CUST_B 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, H - NHRP, l - LISP a - application route + - replicated route, % - next hop override, p - overrides from PfR Gateway of last resort is not set 10.0.0.0/32 is subnetted, 1 subnets B 10.0.0.1 [200/2] via 3.3.3.3, 00:02:24 172.16.0.0/16 is variably subnetted, 3 subnets, 2 masks C 172.16.25.0/24 is directly connected, GigabitEthernet0/2 L 172.16.25.1/32 is directly connected, GigabitEthernet0/2 B 172.16.37.0/24 [200/0] via 3.3.3.3, 00:02:24a CE: interface Loopback0 ip address 10.0.1.1 255.255.255.0 ! interface GigabitEthernet0/0 ip address 172.16.25.2 255.255.255.0 duplex auto speed auto media-type rj45 no cdp enable ! router eigrp 100 network 10.0.0.0 network 172.16.0.0 Router#show ip eigrp neighbors EIGRP-IPv4 Neighbors for AS(100) Router#SHOW IP route 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, H - NHRP, l - LISP a - application route + - replicated route, % - next hop override, p - overrides from PfR Gateway of last resort is not set 10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks C 10.0.1.0/24 is directly connected, Loopback0 L 10.0.1.1/32 is directly connected, Loopback0 172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks C 172.16.25.0/24 is directly connected, GigabitEthernet0/0 L 172.16.25.2/32 is directly connected, GigabitEthernet0/0 Router#ping 172.16.25.1 Type escape sequence to abort.

Hello @i_hanu
Adjust on PE EIGRP process under address family ipv4... add command
af-interface Gig 0/2
no passive-interface

- @i_hanu You need to ensure the EIGRP Autonomous System numbers match between the PE and CE for VPN_CUST_B
.
Modify the PE's EIGRP configuration for VPN_CUST_B
to match the CE's EIGRP AS (100).
PE:
...
!
router eigrp 100 <-- Change from 1 to 100
!
address-family ipv4 vrf VPN_CUST_B autonomous-system 100
redistribute bgp 123 metric 1 1 1 1 1
exit-address-family
