hej,
Chciałem zestawić między routerem 1000v a XRv sesje bgp + MPLS. Konfig poniżej:

1000v

na R1 - czyli 1000v mam w vrfie 004 sieci po eBGP z innego routera. Chciałbym je zaimportować do routera R2 (xrv) przez MPLS. Niestety przy zestawieniu sesji iBGP na R1 dostaje komunikat:

Maszyny są na ESXi postawione, oczywiście interfejsy się pingują, jednak sesja iBGP się nie zestawia.

Gdzie masz w ogole loopbacki ? bo z konfiga wynika ze nie masz

*Mar 7 18:43:25.129: %BGP-4-VPN_NH_IF: Nexthop 1.1.1.5 may not be reachable from neigbor 1.1.1.6 - not a loopback

Masz rację, że z tablicy widać, jednak maske w tablicy pokazuje inną niż jest w rzeczywistości.

Ustaw dwa loopbacki 3.3.3.3/32 i 2.2.2.2/32. Ustaw statyczny routing badz dynamiczny. Uzyj ich do sesji vpnv4 i do MPLS LDP. W konfigu BGP update-source na lo0

na XRv

router static
address-family ipv4 unicast
3.3.3.3/32 1.1.1.5

na IOS-XE
ip route 2.2.2.2 255.255.255.255 1.1.1.6

Edit- zmiana adresow dla loopbackow bo uzywasz juz 1.1.1.1 dla sesji VRF do klienta
