Hello everyone,
I am a beginner in the subject of VRFs, so please be understanding.
Here are my tasks to do:
- possibility of connecting many of the same subnets 192.168.50.0/24 to one router
- ensuring communication between them through NAT
- ensuring multicast connectivity between 192.168.50.100 servers (over static NAT) and other VRFs.
I managed to ensure unicast communication between all VRFs, unfortunately multicast transmission does not go beyond the given VRF.
Can I ask for help, what should be done to make multicast communication available?
Here is my router setup.
ip vrf RD_VRF
rd 65000:1
route-target export 65000:1
route-target import 65000:1
!
ip vrf S10_1_VRF
rd 65000:32
export map to_RD_VRF
route-target export 65000:32
route-target import 65000:1
!
ip vrf S20_1_VRF
rd 65000:21
export map to_RD_VRF
route-target export 65000:21
route-target import 65000:1
!
ip vrf S20_2_VRF
rd 65000:19
export map to_RD_VRF
route-target export 65000:19
route-target import 65000:1
