Hey folks, I read ISIS establishes 2 BFD sessions when activated for both ipv4 and ipv6 address-families: https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_bfd/configuration/xe-17/irb-xe-17-book/ip6-bfd-isis-client.html#GUID-040DB306-4ED5-404...

Hey folks, I read BFD work across bundled interfaces for ISIS, OSPF and static routing. Now considering that on bundled interfaces you can configure a vlan, does that mean BFD works for layer 2 for ISIS and OSPF? The configuration guide says that but...

Hey folks, OverviewI have the following topology where as300 runs ISIS L2 + SR. The device iosxrv5 is connected to AS100 via BGP-LU. The device iosxrv4 is the SRMS for the prefixes received from the AS100 internally. On iosxrv5 I am redistributing ...

Hey folks, I have a curiosity and haven't had the chance to try this live given it's hard to saturate a link in my lab lol If I have the following topology with the numbers being the ISIS metric for the given links: DC0 r1-------50-----------r2--DC...

Can you please share more of your config? Something like 'show run router static' ?

Hey, glad you got this sorted this. I guess the lack of MPLS level config under the tunnel interfaces and absence of mpls traffic-eng tuning around delay made me realise this was an EIGRP level issue and that MPLS was not in the picture at all in thi...

The title is misleading as this seems to be a MPLS traffic-erng issue until one looks at the config. This is an eigrp issue you are having right? If not, please share the actual mpls traffic-eng config. Regardless.. please provide outputs indicated b...

Hey Harold, looking through some more Juniper documentation, I found that: -CSPF prunes the traffic engineering database of all the links that are not full duplex and do not have sufficient reservable bandwidth. So from this, my understanding is that...

I read the paper and it seems the bottom line here is, BFD helps detect layer 2 failures but essentially just work enabled on upper layer protocols. Therefore I am assuming the answer to my question is no, despite ISIS and OSPF supporting BFD over bu...
