I have the following topology
vMX1 advertises 126.96.36.199, when R5 receives 188.8.131.52, what should the next-hop point to by default? ge-0/0/1 on vMX3 or ge-0/0/0 on vMX1?
thanks in advance !!
If JUNOS default settings are used everywhere, then it would be IP address on VMX1 ge-0/0/0.
JUNOS does not change NH when advertising from eBGP to cBGP/iBGP, and does not change it when adverting within cBGP.
