You should talk to your network provider and ask them whether they  
want you to do multilink PPP or IEEE 802.3ad link aggregation.  Either  
way, the bonding of the two connections should give you a single  
virtual network interface (tunX for the first, probably, and laggX in  
the second case) which has only a single route.

For example: http://www.juniper.net/techpubs/software/erx/junose80/swconfig-physical/html/ethernet-config14.html

...talks about "After you configure the LAG bundle, you can route IP  
traffic over it, create a VLAN over it, or route PPPoE traffic over it."
