Hai guy, someone can help me about my problem ?. I'm really confused

When we test any mpls prefix we use source in ping and traceroute to specify IP reachable by test router

Hi @TegarSaputra ,

TGRPE01 does not have any interface in VRF TESTING. You could add a new loopback interface and configure it inside VRF TESTING. This should  fix the issue.

Regards,

[TegarSaputra]

Thanks sir, it's work. Can i know for the reason ?

[MHM Cisco World]

He dont need LO 
he already redistribute connected 
he can use 

ping x.x.x.x source <connect interface IP>&nbsp

;

@TegarSaputra as I mention you need to use IP reachable from the test router. 
MHM

[TegarSaputra]

Thanks for your answer, but i tried add some subif with same VRF. And it worked. Like mr @Harold Ritter says.

[Harold Ritter]

Hi @MHM Cisco World ,

How will TGRPE01 select a source address for the ping or traceroute if it doesn't have a local address it could use inside the VRF?

Now I see he share the

show ip vrf 
but 
vrf TESTING
rd 15:10
address-family ipv4 unicast
redistribute connected <<- this one make him have interface in this VRF ?
redistribute static

@TegarSaputra are you use eBGP between CE and PE ?

MHM

[TegarSaputra]

Oh, i'm not yet configure to CE. Just wanna makesure VRF connected at IGP. 

[MHM Cisco World]

if that case and for test only as @Harold Ritter  mention add LO to vrf and use it as source in ping. 
thanks for clarify 
have a nice day 

MHM
