junOS error: Cannot parse routing-option max-interface-supported

While i was testing multicast in a Olive version i faced the issue bellow, but exists a KB20977 to fix it. The difference here is because i´m using OS 12.1 in a Olive box…

There are 2 ways to fix this, or you use a static dummy route (pex or configure a hidden command.

root@R2# run show version
Hostname: R2
Model: olive
JUNOS Base OS boot [12.1R1.9]
JUNOS Base OS Software Suite [12.1R1.9]
JUNOS Kernel Software Suite [12.1R1.9]
JUNOS Crypto Software Suite [12.1R1.9]

Config OSPF and PIM

lab@R2# set protocols ospf area 0 interface all
lab@R2# set protocols pim interface all mode sparse
lab@R2# commit
error: PIM: Cannot parse routing-optionmax-interface-supported
error: configuration check-out failed


There are two workarounds for this issue:

  • Configure any dummy route under [edit routing-options static]:
set routing-options static route reject
  • Alternatively configure the following hidden command:
 set routing-options max-interface-supported 0

I choose the second workaround and commited the config without problems

lab@R2# set routing-options max-interface-supported 0
lab@R2# commit
