Description

Cannot create two GRE tunnels to the same DST but from different SRC addresses
Configuration:

set interfaces ethernet eth1 address '10.0.0.2/24'
set interfaces ethernet eth2 address '10.0.1.2/24'
set protocols static route 0.0.0.0/0 next-hop 10.0.0.1

Adding tunnels

set interfaces tunnel tun100 address '192.168.8.100/31'
set interfaces tunnel tun100 encapsulation 'gre'
set interfaces tunnel tun100 ip adjust-mss '1436'
set interfaces tunnel tun100 remote '10.0.10.2'
set interfaces tunnel tun100 source-address '10.0.0.2'

set interfaces tunnel tun102 address '192.168.8.104/31'
set interfaces tunnel tun102 encapsulation 'gre'
set interfaces tunnel tun102 ip adjust-mss '1436'
set interfaces tunnel tun102 remote '10.0.10.2'
set interfaces tunnel tun102 source-address '10.0.1.2'

After adding such interfaces manually everything works. I can ping all remote sites through tunnels.
