Hey all, I am labbing up an mx to load balance out two isp connections with a redundancy IBGP link between the two MX L-sys. for some reason i cannot get the isp route to stay the active default route, the backup mx keeps selecting the master mx as its next hop for a default route...config and show route posted below, the L-sys are physically cabled together so no lt interface is needed. Curiously, when restart routing is run the ebgp route will be selected for about 5 seconds buring the routing restart but then will be discarded from the routing table...
CONFIG, SHOW ROUTE AND SHOW INTERFACES TERSE DELIMINATED BY BAR OF **************
