Summit X460.
Scheme:
X460-1 (loopback vlan) <-> (ospf+mpls+ldp)<->X460-2 (loopback vlan) <-> (ospf+mpls+ldp) <-> cisco 7301
All work fine beetween X460-1 and X460-2; X460-2 and Cisco
All routes is present, protocols working, labels is running, BUT when enable iBGP session beetween X460-2 and Cisco, there is no connection beetween X460-1 and Cisco.
Is there some nuances or ideas?
Than you!

I can ping when configured mpls+ospf without bgp.
When enable bgp I can't ping (but routes is present)
Now I can ping 192.168.89.253 but can't ping 192.168.88.226

Not being able to ping means you have another issue than BGP. Your ping should work through the IGP (OSPF). If you can't ping the loopback of the Cisco, you won't be able to establish a BGP session with it.
Do you have a route to that loopback? ie is the loopback announced in OSPF by the Cisco router?

But there is processes BGP and BGP4.
Also in situation:
irtual-router BBBB
configure bgp AS-number 45800
configure bgp routerid 10.20.1.121
or chane to
irtual-router BBBB
configure bgp AS-number 45800
configure bgp routerid 192.168.88.241
(or when I have previous config)
I have situation:
- From 192.168.88.241 I can ping 192.168.89.254 and 192.168.89.253, but can't ping 192.168.88.226
Thank you!

The VPN-VRF are children of the VR, and in that respect they are using the same BGP process. This is why you have to have the same BGP settings (ASN, RouterId).
You could create several VR (user VR as we say) and have different BGP process in each one, and then each would have a different RouterId.
Be aware that only one VR can have MPLS, though.
