As per the below document , this seems to be an expected behavior
http://www.juniper.net/techpubs/en_US/junos14.1/information-products/pathway-pages/mc-lag/multichassis-link-aggregation-groups.html
" If you are using the VRRP over IRB or RVI method to enable Layer 3 functionality, you must configure static ARP entries for the IRB or RVI interface of the remote MC-LAG peer to allow routing protocols to run over the IRB or RVI interfaces."
Dynamic ARP resolution over the ICL interface is not supported.
I have added the configuration for static mac entries and ping to the VRRP address started working.
Configuration added :
