This whole protecting/verifying redundant customer functionality is a
difficult problem.
I have found it difficult to implement mechanisms that detect all possible
faults on the main connection without making things very complicated.
Mostly for remote areas where there is only one local POP that i
In my case, the best result would be to simulate taking the entire device
offline, but I don't know if that's possible to reverse quickly. Taking the
interfaces down would be great. Really, the simplest thing to do is just
spend a minute to create a SMOP that shuts down the interfaces and be done

Hello,
Excuse my ignorance, as this is my first time working with BGP outside of a
lab.
I am working on an ASR that is in use as a BGP peer to an ISP and also an
EIGRP neighbor to an internal network. I have setup this router for
NAT/PAT and all is working well for the internal private subnets.
This raises a good point.
Is the goal to simulate a black-hole that could be seen with an incorrect
adjacency, where control plane is healthy but data plane is broken, or is
the goal to simulate taking this device offline?
Do we care about carrier on the interfaces?

null0 doesn't cause the NHRP to trigger IMHO this will be a disaster .
shut / no shut is the easiest but it doesn't simulate the whole part. real
test comes when the modules crash when reloading specially after couple of
years... :)
what if we copy a empty config ??? and rollback the config ? i
I have wondered the same thing (on C6K/N7K.)
I have since given up wondering and stick to using "ospf max-metric" "int
range shutdown"
That atleast works whilst exposing us to the minimum amount of surprise
code features.
Given enough time, I'm sure SDN/OpenFluff will solve these kind of proble
Copy/paste a bunch of null0 routes?
deny any acls on interfaces?

Been stuck for over an hour on the following:
On a ASR9k (4.1.2) acting as RR i 'm getting IPv4 next-hops instead of
IPv4-mapped ones, although the 6VPE router (ASR001, 15.1(3)S3) seems to set the
next-hop as it should.

We need to upgrade some ASR9Ks that have a lot of connected devices with
complex interrelationships and we have to do a lot of work to make sure all
the correct redundancy is in place prior to the upgrade. Since the router
takes so long to reload, I'd like to find a way to essentially simulate the
Oh yes,
I don't understand why "ipv4 conflict-policy static" and "ipv6
conflict-policy static" is not part of the default configuration
The default behavior makes no sense.

Hello,
We need to terminate a lot of double tagged vlans on ASR1K devices
(ASR1006/ESP20)to provide pppoe/dhcp connectivity.
Currently we work with sub-interfaces but as it is difficult to manage and
maintain thousands of sub-interfaces we are looking for a better way to
implement this.

Hello Ben,
It will load-balance between a path learned from a CE via eBGP as well as
the one learned from other PEs via MP-iBGP to which the CE has a redundant
connection to.
This was actually used prior to PIC to program both paths into the HW in
order to achieve fast convergence.
