Hello All,
I have configured the following setup.
XR1 and XR2 has ebgp session.
XR1 and XR3 has ebgp session.
XR2,XR3, XR4 and XR5 are ibgp neighbors. XR4 is the RR.
XR1
/. \
XR2 XR3

XR4

XR5
XR1 is advertising 1.1.1.1.
I have configure bgp additional path on XR4 and XR5 so that XR5 has multiple paths for 1.1.1.1.

But still, I see only one path on XRV5. I am not sure what configuration am I missing ?
