This terminology is due to historical reasons. In the early days of the LISP Beta network, all xTRs were Cisco routers without hosts behind them. In order to have a pingable EID, a loopback interface was configured with the first available EID from the prefix. > > I understand that a lispmob xtr is supposed to encapsulate/decapsulate > all ingress/egress traffic. Well, most of it. It should only decapsulate traffic destined to an EID prefix that it is responsible/configured for. And it only encapsulates all traffic, if it is configured with a proxy-ETR, otherwise it can also forward natively traffic towards non-LISP destinations. > Does it mean that nodes behind xtr do not need to be mobile nodes and > they need to be assigned EIDs from xtr's EID-prefix (EID-prefix: > 153.16.49.224/28, EID-prefix ipv6: 2610:D0:2164::/48)? Yes. Although recursive LISP encapsulation is also possible. -Lori > > Regards, > Artur
