BGP vpn instance multicast
Hello guys !
I'm not familiar with HP and I would like some advice from you for this issue.
I have a HPE device which is connected to :
- a Cisco router with a BGP session between them (Let say CISCOBGP)
- a Cisco router with OSPF (Let s say CiscoOSPF)
And, in theory, I could receive multicast stream from the Cisco with OSPF and from the Cisco with BGP (CiscoOSPF is link Master / CiscoBGP is link backup)
With, the OSPF everything is fine, I receive my multicast route and my multicast routing table is filled. But with CiscoBGP, I think, I have a problem with my BGP configuration, but I don't know where cause the multicast routing table is empty.
I'm working in a vpn-instance.
My configuration :
ip vpn-instance WORK
multicast routing vpn-instance WORK
OSPF :
ospf 1 router-id 105.7.0.1 vpn-instance WORK
non-stop-routing
import-route direct cost 5 type 1
import-route static cost 1
filter-policy route-policy IMPORT_WAN import
area 105.7.0.0
network 105.7.70.232 0.0.0.3
#
interface Vlan-interface4
description WAN_JUNIP
ip binding vpn-instance WORK
ip address 105.7.70.234 255.255.255.252
ospf cost 10
ospf network-type p2p

#
interface Ten-GigabitEthernet1/0/1
port link-mode bridge
description WAN_JUNIP
port link-type trunk
port trunk permit vlan 4
The multicast routing table is filled. -> display multicast vpn-instance WORK routing-table
BGP :
bgp 60000 instance WORK
router-id 105.7.0.1
timer keepalive 10 hold 30
peer 105.7.70.221 as-number 60000

With this configuration, I received the multicast route on the BGP routing table from the CiscoBGP
show bgp instance WORK routing-table ipv4 multicast
Total number of routes: 2
BGP local router ID is 105.7.0.1
Status codes: * - valid, > - best, d - dampened, h - history
s - suppressed, S - stale, i - internal, e - external
a - additional-path
Origin: i - IGP, e - EGP, ? - incomplete
Network NextHop MED LocPrf PrefVal Path/Ogn
* >e 105.100.1.0/24 105.7.70.221
* >e 105.47.2.40/29 105.7.70.221
But, the multicast routing table is empty (if I've deactivate the OSPF connexion before..) :
display multicast vpn-instance WORK routing-table
(*nothing, just my criyng eyes *)
If someone has an idea or see a huge mistake..
Regards,
