Hi Guys,

In H3 3.1, C4C solution have both BGP ipv4 and vpnv4. However if I just config BGP vpn4 and let add ipv4 blank, MPLS still working well.
So Do we just need vpnv4 in MPLS?

For MPLS we don't require IPv4. We only require IGP (OSPF), LDP and MPBGP (VPNV4). However if in the question it is asked to configured IPv4 then we have to configure it. But it is not required for MPLS to work.

Vpnv4 will build upon ipv4, no way have to have vpnv4 without ipv4

I just checked spoto solution. In H3, Spoto dont have BGP ipv4. They do #no bgp default ipv4-uni and #add vpnv4.

It depends on Requirement. In H3, Cisco ask you both IPV4 and VPNv4.

If you issue no bgp default ipv4-uni, then ipv4 will automatically be created.
