Hi,I am unable to think of scenarios where suppress-inactive is of any use.I understand what the command does and how it works, i.e. suppress rib-failed BGP learned routes due to an IGP with a lower AD being in the RIB and whose next hop differs from...
Hi,I've been doing BGP multipath labs and it seem that step 8, lowest IGP metric to the next hop, is skipped when you are using multipath eibgp.For example, R8 (below) has two neighbours - 9.9.9.9 which is iBGP, and 11.11.11.11 is eBGP:R8#sh run | s ...
Hi,I'm confused as to the reason for the existence of the BGP Cost community.Surely what it does can be achieved by using path attributes. E.g. weight, if you only want to influence a single router, or local preference if you want to affect the entir...
Hi anyone,Quick question, but am I right in assuming that the purpose of Split Horizon in EIGRP is to suppress unnecessary updates rather than to prevent routing loops?DUAL (and the FC) seems to take care of routing loops, so I'm thinking that is its...
Hi,I'm noticing some odd behaviour with regard to a transit area and it not conforming to RFC2328 on the network below: I have a virtual link between R1 and R2, which works, but R1 seems to be advertising a Summary LSA into Area 1 for the network bet...
Hi Paul,I was referring to the #8 IGP metric (not the MED) and it not being equal, and as to why multipath still continues. But after closer inspection I found the answer in Cisco's best path algorithm documentation:7. Prefer eBGP over iBGP paths.If ...
Hi @Peter Paluch ,Thank you for the explanation, makes sense and helps me to further my understanding.Does that mean even with K values set to default, a change in Load or Reliability can still trigger updates? Or are the triggered updates restricted...
Hello @Peter Paluch,Thanks for explaining the MTU.Are the Reliability and Load values the taken from the interface(s) connecting to upstream neighbor(s) that advertise the route, or are they the lowest/highest values along the path? Unlike MTU they c...
Hi,I have another question about this.Is the MTU included in the update the lowest value in the path to the destination network (like BW)? The same goes for load and reliability, are the highest/lowest values along the path to the destination network...
Hi,I know this is an old post but I came across it as I am trying to understand the practical application of having the same network ID on different multipoint GRE interfaces on a single hub.As the mapping database is now shared, does that mean that ...
