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 127.1.1.1) 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 [edit] lab@R2# set protocols pim interface all mode sparse [edit] lab@R2# commit error: PIM: Cannot parse routing-optionmax-interface-supported error: configuration check-out failed
Solution
There are two workarounds for this issue:
- Configure any dummy route under [edit routing-options static]:
set routing-options static route 127.1.1.0 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
