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 127.1.1.1) or configure a hidden command.

[email protected]# 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

[email protected]# set protocols ospf area 0 interface all
[edit]
[email protected]# set protocols pim interface all mode sparse
[edit]
[email protected]# 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

[edit]
[email protected]# set routing-options max-interface-supported 0

SDN and Python in Coursera coming soon

Time to learn different things, this time i will learn SDN concepts and re-learn how to programming but in Python… Yes, i did a lot of programming while i was taking my degree at University using Java,C,C++, PHP and other technologies.

I heard really good things from my friends who took courses on Coursera, so i decided to try it.

Software Defined Networking by Georgia Institute of Technology

About the Course

This course introduces software defined networking, an emerging paradigm in computer networking that allows a logically centralized software program to control the behavior of an entire network.

Separating a network’s control logic from the underlying physical routers and switches that forward traffic allows network operators to write high-level control programs that specify the behavior of an entire network, in contrast to conventional networks, whereby network operators must codify functionality in terms of low-level device configuration.

Logically centralized network control makes it possible for operators to specify more complex tasks that involve integrating many disjoint network functions (e.g., security, resource control, prioritization) into a single control framework, allowing network operators to create more sophisticated policies, and making network configurations easier to configure, manage, troubleshoot, and debug.

 Course Syllabus

This course will cover 8 modules (one per week).

Module 1: History and evolution of SDN

Module 2: Control and data plane separation

Module 3: Control Plane

Module 4: Network Virtualization

Module 5: Data Plane

Module 6: Programming SDNs

Modules 7: Verification and Debugging

Module 8: Use Cases and Looking Forward

Recommended Background

Students should have taken at least an undergraduate-level networking course and have programming experience in Python. Experience with virtual machines and other virtual networking environments may also be useful.

Suggested Readings

There are some useful videos available online; these might be a good starting point for many people:

You may find the additional reading useful for introductory material:

Course Format

The course will consist of a series of video lectures, each about 10 minutes in length.

Assignments for the course are lab-based programming assignments, many of which build off of the Mininet software developed at Stanford University, which can run SDNs in emulated environments on networks of virtual machines.
