HI Rafael, This behavior is not a bug, is an expected condition. ASR 900 routers are not designed to handle more than 20k routes because they are placed on the Edge as PEs. if you have more than 20k routers, consider to implement some filtering options to improve the performance of the router. This is a model comparison of the ASR 920 family: https://www.cisco.com/c/en/us/products/routers/asr-920-series-aggregation-services-router/models-comparison.html Regards, ... View more

Hi nwilson,   what you can do is to create a specific VRF for management and attach a loopback interface to it. Then redistribute that loopback into BGP.   There is a quick guide of how to implement L3VPN for your use case:   https://www.cisco.com/c/en/us/td/docs/routers/asr920/configuration/guide/mpls/mp-l3-vpns-xe-3s-asr920-book/mp-multi-vrf-vrf-lite.html   regards, ...

Hi Nuhu,   " rewrite ingress tag pop 1 symmetric" is not required for your use case. Because you are matching and dropping packets with tag 200, 300 or 400.   "rewrite ingress tag pop 1 symmetric" will be useful if you need to handle different services across the MPLS cloud.   regards, ...

Hi Andrés,   You can perform ISSU (In Software Service Upgrade) installation with minimal disruption in a single step or as multiple phases. You need to perform the pre-installation tasks before executing ISSU. During the pre-installation tasks and ISSU execution, V1 refers to the image currently running on the router and V2 will be the upgraded image.   ISSU execution contains the following phases: Prepare phase: The installable files are pre-checked and loaded on the router before activation. This phase is optional. Activate phase: The new image (V2) is downloaded to all nodes in the router replacing the old image (V1). This phase can be run in step-by-step phases like   Load ,   Run , and   Cleanup   or by using a one-shot   Activate   phase. Commit phase: The ISSU installation is complete with V2 on all nodes. Besides, IOS-XR can abort the upgrade if something is wrong and rollback to the V1.   https://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k-r6-4/system-management/configuration/guide/b-system-management-cg-asr9000-64x/b-system-management-cg-asr9000-64x_chapter_010111.html#id_91543     ...
