For those of you interested in all the details around how the transit as well as host-inbound and host-outbound traffic is handled on juniper MX3D Trio architecture I'd recommend reading the following FREE book in its entirety. https://www.juniper.net/us/en/training/jnbooks/day-one/networking-technologi es-series/packet-walkthrough-mx-series/ It's an excellent book that will answer, among others, all your questions around where the ICMP might be delayed in the system and where and how it is handled. I'd say it's a must read for all NetEng/Arch working with Juniper MX. adam _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
