for node1:

primary_path:

dlid=0x1f06 slid=0x1d06 raw=0x0 flow=0x0 hop=0x0 tra=0x0  rev=0x1
numb=0x0 pkey=0xffff sl=0x0 mtus=0x2 mtu=0x4 rate=0x2  plts=0x3 plt=0x2 
pref=0x2

alt_path:
dlid=0x2006 slid=0x1e06 raw=0x0 flow=0x0 hop=0x0 tra=0x0  rev=0x1
numb=0x0 pkey=0xffff sl=0x0 mtus=0x2 mtu=0x4 rate=0x2  plts=0x3 plt=0x2 
pref=0x2

they seem to be same,
