thanks kbmoris.
I have read in the NX-OS config guide as well that attaching a layer3 device in a L2 VPC path is not recommended.
thanks for your assistance.

I have updated the diagram for clarity.
Based on the diagram, I thought from the persepective of router below it can form adjacency to both VPC switches (N9500s) on each leg - total of 4 adjacencies. Haven't simulated yet though.
Can your share any docs pertaining to restrictions running dynamic routing protcol over VPC to the VPC switch?

I have Nexus 9500s and 9300s.
VPC enabled.
A router below is dual-homed to the 9300s
L2 Path is provided via VPC from N9300 to N9500.
Since N9500 is the L2/L3 boundary, I would like to establish IGP adjacency as below.
Is this topology/deployment supported?
How will be the behavior of OSPF neighbors, failover in this case?
Please advise, thanks

What about issues on L3 proxy using M cards?
Does F3 has this limitation similar to F2e?

Hi.
Are there restrictions and issues when F3 card is mixed with M2 cards?
I assume there's no more issue of L3 Proxy mode with F3 cards.
Please advise.
thanks

How do we enable bidir in XR if not using static RP?
Looking for the command equivalent to ip pim bidir enable in IOS.

Unable to continue troubleshooting due the project was stopped.
Not sure if there's compatibility issues between XR and NX-OS.

Yup I've read this.
This is what Im referring to.
I have a PE (3.3.3.3) dual homed to two RRs of different cluster-id.
So from RR1, I am receiving two paths.
- one via from the direct RR-client (3.3.3.3)
- one via the the second RR (2.2.2.2)
So all attributes same, even the IGP metric.
RR1 will always prefer the patch via direct RR-client peering.
I am looking for a documentation that says multiple paths via RR-client peer routes is always preferred compared to routes learned by other RR (different cluster-id).
Can you enlighten me here?

Is there any documentation about route preference if there are two routes received to a destination.
Next-hop PE for the destination IP address is same.
1. via direct iBGP peer to its rr-client
2. via ibgp to other Route-Reflector

Hi Experts.
What could be possible reason for receiving incomplete ISIS database from an adjacent ISIS neighbor?
I noticed I am receiving incomplete LSP from an NX-OS ISIS peer compared to a IOS-XR peer which is complete.
Configuration is basic level-2, wide metrics enabled.
Is this related to any ISIS timer, padding, configurations?
Any inputs will be appreciated.
thanks

Hi.
Anyone encountered issues with NX-OS ISIS routing wherein ISIS database learned from an NX-OS device is not being installed in the RIB?
I have few routers; A9K-1 >NX>A9K-2>A9K-3
From A9K-2, I am receiving full ISIS database from NX device but routes not installed in RIB.
WHile I dont have problem among A9Ks.
Configurations are plain pure leve-2 and wide metrics enabled.
any comments and recommendations will be highly appreciated.
thanks

any idea?
By the way, the adjacent router is a Nexus 7710 device.
Only ISIS LSPs coming from 7710 is not being installed in the ASR9K RiB.
I tested to enable ISIS with another adjacent router but this time another ASR9K and works fine.
Is there an issue with Nexus LSP propagation?
